Lizzy Johnson Commits to Florida State for 2028: Re-reading 23.17 and the Two-Second Problem in the 100 Free

Last December, at the RAFC Winter Classic, Lizzy Johnson touched the wall in the 50 freestyle final and the scoreboard read 23.17. It was the first time she had gone under 23.20 in the shortest event. What matters more is the rest of that week: she entered seven events, won the 50 free, finished runner-up in the 200 free and the 100 individual medley, placed ninth in the 100 free and 50 breast, eleventh in the 50 fly and seventeenth in the 100 fly. Four personal bests came out of seven starts, spread across four different distances: 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. Johnson is a junior at Windermere High School in Florida and swims year-round for Lakers Swimming. In recent days she 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 in Tallahassee, and thanked Goller, coach Ali, her friends, Cynthia and her family, along with coaches Kyle, Ben and Neal for giving her the chance to make a lifelong dream real. In the American college sports system, a verbal commitment is not a contract. It is held together by honour and by planning, not by a signature, and it only becomes official when the athlete signs the National Letter of Intent in the final year of high school. For a junior aiming at the 2028 season, the runway ahead is longer than the entire high school career already behind her. That makes this announcement less a signing and more a forecast. The forecast has data to read. At the FHSAA Class 4A State Championships last autumn, as a sophomore, Johnson placed sixth in the 200 free in 1:49.90 and fourth in the 100 free in 51.13. A year earlier, as a freshman, she swam the 50 free in 23.74 for fourth and took eleventh in the 200 free in 1:50.23. In other words, she reached a state final in the shortest event at fifteen, then shifted to the 100 and 200 freestyle the following season. That event shift at the state meet reads like a deliberate technical decision, and the numbers support that reading. Take the gap between the 100 free and twice the 50 free — what I keep calling the "doubling tax". For Johnson, two times 23.17 is 46.34, while her best 100 free is 51.13, a tax of 4.79 seconds. Set that beside the names in Florida State's sprint group: Maryn McDade has gone 22.20 in the 50 free and 49.04 in the 100 free, a tax of 4.64 seconds; Antonina Biegajlo has gone 22.87 and 50.94, a tax of 5.20 seconds. Johnson sits between them. The Gatlin–Coleman equation taught me that speed is never a single variable. In 2026, analysing the men's 100m final in London, I found that Justin Gatlin's reaction was slower than Christian Coleman's, yet Gatlin's stride frequency during acceleration was 0.4 Hz higher. The shortest sprint is decided by reaction and frequency; the doubled distance is decided by the rate of decay. Johnson's doubling tax is lower than Biegajlo's, which means her ability to hold speed is better than her top-end speed. That is not the profile of a pure sprinter. The railway line behind Risdon leads nowhere — that emptiness tells the whole story better than the finish line. Here too, the gaps are the data. Johnson's best 100 free, 51.13, is 2.10 seconds behind Ioana Stirbu and 1.62 seconds behind Mary Leigh Hardman. In the 200 free she is 4.64 seconds behind Stirbu but only 1.44 seconds behind Hardman. Her relative standing flips depending on the event, and that is a more important technical signal than any summary line in the recruiting report. In the 100 fly and the 100 IM the picture sharpens further. A 55.83 in the fly and a 57.38 in the IM are not the marks of a pure sprinter; they are the marks of someone who can swim the fly leg of a medley relay and absorb four events across two days of competition. In November, at RAFC's Almost Turkey meet, she set lifetime bests in the 500 free and the 200 fly. Neither event ever appears in recruiting news, yet both are the aerobic foundation that decides whether an athlete survives four college seasons. And this is where the recruiting report needs to be read slowly. It states that Johnson will join a sprint group that "may still include" McDade, Hardman, Biegajlo and Stirbu. That conditional carries far more weight than it appears to. McDade and Hardman are currently college juniors; unless they redshirted a season to preserve eligibility, they will run out of competition in spring 2027. Biegajlo and Stirbu are currently sophomores, graduating in spring 2028 — before Johnson sets foot in Tallahassee. For any of them to still be there in 2028-29, they would need a fifth year, and that is only possible with a redshirt already used. Put plainly: Florida State is not signing Johnson to add to the sprint group it has. It is signing her to rebuild that group on a different clock. This is not a loose inference — it is simple subtraction between class years and eligibility, something every roster projection performs but rarely writes down as a sentence. Florida State also faces a fact about Johnson's own record: she arrives as depth, not as a headline. A junior with a 51.13 in the 100 free is an asset to a programme that needs to fill relay slots across four consecutive years, not someone who changes the picture immediately in an individual event. The COVID laboratory taught me that data feels pain — if only we listen. In 2026, when global sport stopped and I lost my newsroom job, I messaged Dr Emily Chen at the Australian Institute of Sport to measure ground contact times in fifteen national hurdlers. The then women's 100m hurdles champion averaged 0.088 seconds of ground contact across eight hurdles, 0.012 seconds longer than the theoretical optimum. Nobody saw that hole, because the results still looked good. What I learned was not the 0.012 figure itself, but that the loss always hides in the segment nobody measures. In swimming, the unmeasured segment is the turn, the underwater and the first breakout off the wall. No results sheet prints them. For a young female athlete whose aerobic base is being built through the 500 free and the 200 fly, the turn-and-underwater package is what decides whether 23.17 becomes 22.60 by 2028. Four personal bests in one December week, and two more in a November week, are signs of training volume being fully absorbed rather than of a curve already at its peak. I do not believe in luck; I believe in the lane each athlete chooses to stand up in. Johnson chose Florida State while she is still an open hypothesis, and she surely knows better than anyone that two seconds in the 100 free is a gap closed by technique, not by slogans. Every record is a hypothesis confirmed; every defeat is an equation waiting to be solved again. With a verbal commitment stretching nearly two years ahead, time will be the only judge, and her speed-decay curve — not a social media post — is what will speak last.
