I agree with you that Miami is putting RB's at a high rate. We're still one of the best in the country in overall number of RB's drafted. But we're not at the level of Alabama, LSU, Georgia - and I'd say we're a notch below FSU.
I agree with Rell that you can only sell your program with it's top players. People don't really care about the role players, and I think FSU has been better than us there.
I love Lamar Miller. He has better overall stats than Freeman or Cook, but he was never quite at the level Freeman was for a couple years or Cook has been (when healthy). And those are the guys you need to sell your program.
Miami - Duke, FSU - Chris Thompson. Duke is definitely better - but both a 3rd down types. They're nice players, but you don't get excited about their NFL careers.
Then each have had journeyman types. Miami - Mark Walton, Mike James, Travis Homer. FSU - Antone Smith, Karlos Williams. These are the types mostly just die hard fans remember.
Then both have guys coming - Miami - DeeJay, FSU - Cam Akers.
IMO - having 1 or 2 top guys is a better selling point and more than 4 or 5 role players.
