What would be most likely the difference between a guy that's an ok wrestler and stops when HS ends and someone that will continue to wrestle in College? Is it discipline, talent, athleticism, hard work...? Or is that different for everybody and too hard to answer?
You realize early on if you're good enough to wrestle in college. The best guys at D1 are like 3 time state champions and even then, they might never crack the starting lineup. Competition is that intense. Most people stop at high school since they go off to college and have other things going on.
