Here's the story in full at ESPN. Some highlights are below:

So can we expect a Florida-esque or Utah-esque spread offense at Louisville?

MS: We're going to be a Florida-ish spread offense. You know when people say spread offense, there's a lot of different types and categories and classifications. We're going to be most similar to Florida. Now we don't have a Tim Tebow. I think what you've got to do, and I believe there's enough flexibility in what we're putting in, that we have to cater to our personnel. That's an important thing. You've got to cater what you do in your spread offense to your quarterback and to what kind of receivers and linemen and backs you have. So we're going to tailor it to our personnel.

That system is known for having mobile quarterbacks. Is that what you're looking for here?

MS: I think ideally what we'd like to have is an athletic quarterback that's a really good passer. And I'm very excited about it because I think we've got some guys in the program that can do that. And we also signed a quarterback out of Cincinnati named Dominique Brown who's that type of player.

I'd think that means Froman, because Burke lacks the athleticism and Stein lacks the talent. There should be more coming.
