I think some of what you are sayiing is right. Schiano definately can get away with these 7 win years at Rutgers, they have no fans and the fans they do have are just happy to not be going 3-8 every year.
Where I disagree with you guys, is I believe he is a very overated recruiter. Yes, the talent level is worlds ahead of where they were, but ever since that really good group that almost went to the BCS has moved on, he hasnt followed up. He had 10-12 pros on those teams. How many pros does he have now? No more than one or two.
Schiano is a good (not great) recruiter, a great motivator, a great PR guy, and a below average game day coach. I gave him the benefit of the doubt the first few years, but he is a bad sideline guy. Can't manage the game, does wacky shit that makes no sense.
This is a moot point, Miami isnt hiring him. His name came up last time, too.
