Seems to me it's more of a crapshoot if a school consistently recruits low star recruits. I mean, for example, Micah Hyde of Buffalo wasn't even a DB in high school, I'm told, he was a QB. Talk about the low success that transformation usually entails. Going from non-existent in the defensive backfield to the pros? Wouldn't it be nice if Iowa were able to recruit high skilled athletes for positions they'll play in college?
The higher the star, the more athletic and proficient the high school recruit is.
This is the only thing proven with the star system and a KF-type of program: No doubt the lower star recruit has more success in a KF-type program and conversely a KF-type program doesn't have much success with a high star recruit (so they usually, eventually, transfer).
