Lizzy Johnson Commits to Florida State for 2028: The 23.17-Second Equation and Sprint Group Depth

In the 100 freestyle final at the FHSAA Class 4A State Championships, Lizzy Johnson touched the wall in 51.13 seconds and finished fourth. At the same meet, in the 200 freestyle, she placed sixth in 1:49.90. For most spectators, those are two lines of results that scroll by in an evening. For a small group of people who work with swimming data, they are two anchor points for reconstructing an athlete's trajectory over the next four years.

Last fall, as a sophomore at Windermere High School in Florida, Johnson finished inside the state's top six in both freestyle events. A year earlier, as a freshman, she took fourth in the 50 free at 23.74 and eleventh in the 200 free at 1:50.23. In December, at the RAFC Winter Classic, she won the 50 free and posted a stack of personal bests: 23.17 in the 50 free, 1:49.61 in the 200 free, 55.83 in the 100 fly and 57.38 in the 100 IM.

Earlier this year, Johnson, now a junior who trains year-round with Lakers Swimming, announced a verbal commitment to swim and study at Florida State University beginning in 2028. On social media she wrote that she was overjoyed to continue her academic and athletic career at Florida State, thanked coach Goller, coach Ali, coach Kyle, coach Ben, coach Neal, her friends, Cynthia and her family, and closed with GO NOLES and three emoji.

A verbal commitment at 16 or 17. A four-year timeline. And a question the numbers can partly answer: what does 23.17 seconds buy in Florida State's sprint group?

How the American college recruiting system works

In American school sports, a high school athlete can make a verbal commitment to a university before graduating, usually in the tenth or eleventh grade. That commitment carries no legal weight. It only becomes official when the athlete signs a National Letter of Intent in the final year. The gap between those two milestones typically runs from 18 to 30 months, and during that window everything can change: injury, a coaching change, a better offer, or simply a family conversation on a Sunday evening.

Johnson belongs to the class of 2028. She will leave high school in the spring of 2028 and arrive in Tallahassee that fall. While she waits, she keeps swimming for Lakers Swimming, keeps competing at FHSAA meets, and keeps having to prove that 23.17 is not the peak of a curve but a point in the middle of one.

American school swimming is measured in yards, not metres. A pool is 25 yards long, and events are timed in that unit. A 50-yard freestyle is roughly four and a half metres shorter than a 50-metre freestyle, so yard times cannot be compared directly with metre times. This is the detail most readers skip when they see 23.17 and rush to place it next to an Asian or Olympic record. Two measuring worlds, two distributions of results, two frames of reference.

Vietnam has no equivalent structure to the American college sports recruiting pipeline. A Vietnamese swimmer enters the youth national pathway much earlier, tied to national training centres and the regional competition calendar. Names like Nguyen Thi Anh Vien, Nguyen Huy Hoang and Tran Hung Nguyen grew up in a different pipeline, where a university scholarship is not the final reward of a career. A commitment like Johnson's is, structurally, a product of a very specific ecosystem in which the university is simultaneously a place to study, a place to compete at the highest level, and a launchpad for a professional life.

On the Florida State side, the university's swimming and diving teams compete in the Atlantic Coast Conference, one of the most densely competitive leagues in American college swimming. The recruiting problem for a coach here is not finding the fastest swimmer. It is finding the fastest swimmer at the exact moment the roster needs one, at a workable scholarship cost, and with an improvement curve that has a higher probability than the rest of the age group.

Lizzy Johnson's number chain: three seasons, four events, one question about the ceiling

Based on my experience tracking school and international swimming meets, the way to read a young swimmer's profile is not the single best number. It is the shape of the number chain over time. Johnson gives us three school data points and two club data points.

Point one, freshman season: 23.74 in the 50 free, fourth in the state; 1:50.23 in the 200 free, eleventh. A solid start, but not yet a start that draws national attention.

Point two, sophomore season: 51.13 in the 100 free, fourth; 1:49.90 in the 200 free, sixth. She jumped from eleventh to sixth in the 200 free and shifted her focus from the 50 free to the 100 free. That shift in distance, at 15 or 16, is usually the sign of an athlete beginning to build an aerobic base rather than relying purely on raw speed.

Point three, the personal bests from the RAFC Winter Classic in December: 23.17 in the 50 free, 1:49.61 in the 200 free, 55.83 in the 100 fly and 57.38 in the 100 IM. She won the 50 free, was runner-up in the 200 free and the 100 IM, took ninth in the 100 free and the 50 breast, eleventh in the 50 fly and seventeenth in the 100 fly. In November, at the RAFC Almost Turkey meet, she set lifetime bests in the 500 free and the 200 fly.

The first notable thing is the range. A 16- or 17-year-old appearing in the 50 free, 100 free, 200 free, 500 free, 100 fly, 200 fly, 100 IM and 50 breast is an athlete who has not yet specialised. At this stage, breadth is an asset. It lets a college coach try several relay configurations and keeps the athlete from being locked into a single window of improvement.

But breadth is only an asset up to a point. At 19 or 20, breadth becomes an opportunity cost. Every minute spent on breaststroke is a minute not spent on freestyle. Johnson's real problem over the next two years at club level is not how many events she can swim, but choosing the right two to invest in.

The second notable thing is the ratio between events. In the 50 free she has gone 23.17. In the 100 free, the best figure the source records from the early season is 51.13, although at the RAFC Winter Classic she only placed ninth in that event. In the 200 free she has gone 1:49.61. Read as a ratio, her 200 time is only about 4.9 times her 50 time, a ratio that points to a comparatively solid aerobic base relative to pure speed.

The third and perhaps most important thing for a university is the age at which those times were swum. If 23.17 in the 50 free and 55.83 in the 100 fly were set at 15 or 16, the room for improvement over the next three years is a variable worth more than the current number itself. A scholarship does not buy today's performance. It buys the probability distribution of performances over the next four years.

Benchmarking against Florida State's current sprint group

A contract is not a signature; it is a hypothesis that has been signed. That hypothesis can only be tested against the group the athlete will join.

According to the recruiting report, the Florida State sprint group Johnson may join includes juniors Maryn McDade at 22.20 in the 50 free and 49.04 in the 100 free, and Mary Leigh Hardman at 49.51 in the 100 free and 1:48.17 in the 200 free, along with sophomores Antonina Biegajlo at 22.87 in the 50 free and 50.94 in the 100 free, and Ioana Stirbu at 49.03 in the 100 free and 1:44.97 in the 200 free.

Put those numbers side by side and the picture is far clearer than a short news headline suggests.

In the 50 free, Johnson has 23.17. McDade has 22.20. The gap is 0.97 seconds. At an average speed of roughly 1.97 metres per second over a 50-yard course, that is nearly two metres, about one body length in the pool. Biegajlo has 22.87, 0.30 seconds ahead of Johnson, roughly half a metre, a gap that can close inside one training cycle.

In the 100 free the gap widens. Johnson has 51.13 from the state meet, while McDade has 49.04, Stirbu has 49.03 and Hardman has 49.51. The differences are 2.09 seconds, 2.10 seconds and 1.62 seconds respectively. Over a 100-yard race, two seconds belongs to a different tier, not to a different training season.

The 200 free partly reverses the story. Johnson has 1:49.61, 1.44 seconds behind Hardman but 4.64 seconds behind Stirbu. In other words, the 200 free is not where she can break into a relay immediately, but it is also not where the relative gap is largest.

Read as a whole, a pattern emerges: Johnson's distance from the current sprint group grows as the event gets shorter and shrinks as the event gets longer. She is closest in the 50 free and furthest in the 100 free. That is a fairly common shape for a young swimmer who has not yet refined her starts and underwaters, two factors that carry a large share of a 50-yard race.

There is a timing detail the model has to account for. The two juniors in the group, McDade and Hardman, will graduate before Johnson arrives in Tallahassee. Biegajlo and Stirbu, the two sophomores, will also finish their college careers around the point where Johnson begins hers. That makes this commitment more of a succession plan than an immediate addition. The Florida State staff is not buying a slot in next season's relay. It is buying a slot in a relay four years from now, when the current group has moved on and the depth of the sprint roster needs to be rebuilt.

This is the kind of decision that data supports better than instinct. An athlete who finished fourth in the state in the 100 free as a sophomore, and who owns personal bests across four different events as of December, is an asset with a high expected return over a four-year window. Nothing guarantees she will swim 49 seconds in the 100 free in 2029. But the probability that a swimmer with that curve reaches the 50-second threshold is meaningfully higher than for a swimmer outside the state's top ten at the same age.

Conditions for the prediction to hold

Any judgement about a young athlete should be filed with conditions attached. For Johnson, the model only holds if three conditions are met.

First, she has to maintain her competition frequency at state level over the next two seasons. An athlete who suffers a shoulder or knee injury at 16 or 17 loses 12 to 18 months of trajectory, and that time is rarely fully recovered.

Second, she has to choose two anchor events. If she is still spread across eight events by her senior year, the probability of hitting a college-level threshold in any one of them falls. If she narrows to the 50 and 100 free, or to the 100 and 200 free, the curve gets steeper.

Third, the commitment has to hold. A verbal commitment is not binding, and in American college swimming today, with the transfer portal and individual commercial agreements in play, an athlete can change her mind for academic reasons, for a better scholarship, or because of a staffing change on the coaching side. I have no data to say whether she will change her decision. I can only say the model has to price that probability in rather than default it to zero.

The counterintuitive angle: the cross-comparison trap and the limits of the model

The easiest way to get a young swimming analysis wrong is to compare numbers drawn from different contexts directly. I have made this mistake myself, and the only fix is to state each number's context before placing them side by side.

A 22.20 in the 50 free might come from a relay leadoff split, where the swimmer benefits from a start into water already moving. Or it might come from a morning heat, with the athlete nowhere near peak condition. Or it might come from a final at the end of a full taper. Three contexts, three meanings, despite an identical figure on the scoreboard.

Likewise, Johnson's 23.17 was set at the RAFC Winter Classic, a December club meet, in the period between the school season and the club season. That is not her physical peak of the year. Her 51.13 in the 100 free, by contrast, was set in a state final after a deliberate taper. The two numbers come from two different physical states, and putting them in the same comparison table without a note is a methodological error.

A second caution concerns causation. Johnson's curve moved from 23.74 to 23.17 in about a year. There is a natural temptation to assign that improvement to a single cause, usually a new coach or a new training programme. The real mechanism is messier: physical growth, height, arm span, training volume, sleep quality, and plain variance between swims. Unless a specific physical mechanism linking cause and effect can be named, the correct phrasing is that two data series are related, not that one produced the other.

And there is a slice of variance the model cannot measure. In her announcement, Johnson writes about a lifelong dream. That is a variable belonging to intrinsic motivation, and it appears in no results table. My data models treat willpower as a constant. In reality it is the variable with the largest variance in the whole system, and also the hardest to measure. When an athlete writes about a dream rather than about a time, that is a signal I can only note, not quantify.

The shot happens once. Its trajectory lasts for years. In swimming, that shot is a 23.17-second lane in a December evening. And that trajectory will be written further in Tallahassee, where every hundredth of a second is paid for with a month of training.

Next-cycle signals

Three signals to watch over the next 18 months, each tied to a specific threshold.

First, the 23.00 mark in the 50 free. If Johnson reaches it in her junior or senior season, her gap to the college sprint group narrows below 0.9 seconds and she becomes a candidate for a 200 free relay slot rather than just a contingency option.

Second, the 50.50 mark in the 100 free. That is the dividing line between an athlete with potential and an athlete with a conference meet slot. If she clears it as a senior, the probability she appears in Florida State's 400 free relay in 2029 rises sharply.

Third, and probably the most strategically important signal, is whether she narrows her event range. If she appears less in breaststroke and short fly next season and concentrates more on freestyle, that indicates the coaching staff has settled on a direction. If she stays spread out, the question of where she fits on the roster extends by at least another season.

Every surprise has its own probability. We call it a surprise only when we have not checked the table yet. A commitment at 16 is neither a surprise nor a miracle. It is a hypothesis that has been signed, and its number table will be filled in over four seasons.

When Johnson arrives in Tallahassee in the fall of 2028, the pool there will not care what she once placed in the state in any event. It will only care which second she touched the wall. And most people watch the goal to understand the match, while I watch the match to understand the years.
