He likes them all. Here's what he said about Nathan Peterman
"He just looks like a pro quarterback -- coming out of the huddle, running an offense with different formations, shifting, motioning, different patterns that other colleges don't run. Peterman will recognize route combinations and associate formations."
"Most importantly, he will be able to get in a huddle from day one and look at 10 grown men and tell them where to go and what to do and handle a versatile snap count," Gruden wrote.
"He is sharp. He is in the channel, I think, of success. I think he's going to be a real good pro quarterback," Gruden said of Peterman, via the Bills official website. "I think any team in the league, you can cater your offense for Peterman. He's a lot more athletic than people think. And he can handle an extensive amount of football, so the teams that are really ambitious with deep, thick playbooks, those are the teams that Peterman would fit in with. But I hope he gets with one of those guys that can really stretch him and challenge him."
