I'm so tired of this argument.
Correlation does not imply causation.
Alabama, LSU, USC, Notre Dame, Michigan, etc. are going to get players that have 4 or 5* because they always get players that have 4 or 5*. However there's a HUGE difference between the 5* players that Charlie Weis recruits and the ones that Brian Kelly recruits. Alabama sucked with 4 and 5* players when Mike Shula was the coach, not so much when Nick Saban is. There very fact that Michigan and Alabama are offering a player means he's going to get 4 or 5*. Not matter how good or how bad the player is. It's more about the coach that's doing the recruiting than the stars the players have.
ALL THAT BEING SAID.... we're not getting those 4* and 5* kids... so this is moot anyway. We've got a coach with a track record of producing NFL players with 2*/3* players. That's literally the best we can hope for until we join a P5 and/or have a couple of New Years Day bowls under our belt... neither of which is happening anytime soon.
