Another consideration would be what it means in terms of day-to-day life, as a D1 vs. D3 athlete. We’ve heard D1 coaches say that their athletes can “pick 2” from among their sport, academics, and their social life and other D1 coaches describe that the sport is about a 40 hour a week “job” in season, with training, competing, travel, meetings etc. D3, especially at an elite academic school like Williams, is about the “scholar athlete” not the “athlete scholar.” Some D3 schools (I don’t know about Williams specifically) do not schedule class after about 4pm so that Varsity athletes (and students involved in other extra curriculars) don’t have to worry about, for ex., conflicts between labs and travel to an away meet. My own D3 athlete (not T&F) spent about 25-30 hours per week in season on his sport and 5-15 hours out of season. Particularly for T&F athletes who might be training and competing for fall, indoor and/or spring season, the time commitment between D1 and D3 could be significant.
No “wrong” choice here, just about finding the right fit! Congrats on two amazing opportunities!
