I will make one final attempt. Wisconsin doesn't produce better football players than Minnesota (see the NFL). Wisconsin highschool players are THOUGHT better than Minnesota because of the success of the Badger program. Once the Gophers start winning (this year) at a higher level. Gopher recruits (highschool football players) will be thought more superior or better. Since the Gophers have more players from Minnesota than any other state, Minnesota highschool football players will receive a boost.
I realize you were not speaking of Florida or Texas, I only offered it up to demonstrate how highschool football players on the same level or below (not the top echelon Florida and Texas players) are assumed better because of the success of the colleges while recruiting predominately from those states.
Now before folks scream, I'm in no way saying that Minnesota is on par with those states. I'm saying that a level of players (after the top 25-50) are incorrectly assumed superior than Minnesota players (ie ranked higher and/or receive scholarships). The same thing applies to Wisconsin players for the same reason, only to a much lessor extent.
How did I do?
