Junior-year marks are the ones coaches see
Recruiting boards get built over the summer off the spring that just ended. A time you run in April of your junior year sits on a coach's spreadsheet for months. Sophomore marks fade quickly, and senior marks often land after the deepest programs have already spent their spots. If you get one clean season, this is it. Division by division, what those marks have to become is set out in college 100m times by division. The next rung up, and the one most boards actually get built from, is the 100m at 17.
