I agree Barnsey, I don't think the gap is as far as it might look. Another thing to remember is that virtually all these recruiting sites are Southern creations. These sites push southern teams and give higher stars to guys who are looking at the big SEC schools. If Alabama is looking at you, you pretty much automatically become a four or five star.
Now, there is certainly some truth to this. These services don't know as much as the coaches so to an extent, if Saban or Meyer chase you thats a better indication of your value then what some schlub who works for Rivals that used to coach high school thinks but the whole star system is quite imperfect.
I remember Malcom Jenkins was 3 star in some services and when he played as a freshman it was obvious the kid knew how to play defensive back form day one.
Ill take our roster right now.
