Id agree with u for almost every other position besides QB, that development starts way before college. Its the hardest position to evaluate and develop, its hit or miss. If a college can get u drafted first round u should go there.
What works in college might not work in the nfl its two totally different situations. If what u saying is the case then literally every college has failed almost every qb they have had lol. Osu at least gets u drafted high some schools u wont even make it to the combine
