What Ty's dad said. First of all, the number of elites in the US program is very small compared to the number of college programs and slots available. Second, as Tys Dad stated, scoring in the college is based on L10 codes with some modification, not elite. So as odd as it may sound, there are a few elite gymnasts that do not make good college gymnasts, since elite scoring is so heavily dependent on difficulty versus execution. Some elites were brought up with just focus on getting a skill and don't worry about form, but in college, there is no reward for doing a very difficult skill so the risk of bad landings, OOB, poor form, etc is not worth it. Some elites have difficulty switching and focusing on form. Now this is a small number but it does reduce the number of elites in the college pool. Compounding that reduction in elites is the propensity for injury in the elite world. This might be improving, but recent history has shown so many elites entering college and having minimal impact due to lingering injuries. For example, Jazmyn Foberg, Madison Kocian, Riley McCusker, Morgan Hurd, etc.
Being elite certainly gets you exposure and that helps in recruitment, but the meat of college rosters are strong L10s.
