Your 1st point goes a long way. Supporting cast. The talent level in college is way greater than in the pros. Tebow has played with the best talent in the nation. While Locker was playing with some of the worst talent is FBS.
Locker is a better athlete than Tebow so if you say their arms are a push Locker should be the better prospect. College numbers are so misleading. It's too much based on supporting cast and systems.
