So you're saying Belichick knew last year that Marrone would be the coach of the Bills this year? If he did, I don't think he needs any information from Schiano.
It's not a difficult concept. You can't give everyone reps and you can only evaluate so many players.
Seriously..it takes like 2 seconds of thought to understand it.
Why don't teams take QBs every year? duuuuuhhhh
