I don't know the exact number of stars with each class...I can look at the roster and pretty much tell you how the kid was rated when he was coming out of HS.
Just as one example, with a Jr. but a kid no one thought highly of that has really come out?
Drew Davis. He was a Rivals 2* coming out of high school...I don't recall if he had any offers from SEC schools much less schools like UNA, etc. Here's a kid that was in the 2004 class, took a grey-shirt, then a red-shirt, and this past season as a Jr. has done a hell of a job considering the problems we've had at RT.
