Osborne was once quoted as saying if he were coaching today he would run a Power Spread Option similar to what Urban Meyer ran at Florida with Tim Tebow. This essentially eliminates having a FB and adds an extra WR and Frost doesn't even have a FB on the UCF roster.
So, if people like Frost and want him here, he'd bring an offense that is a lot like what he and Chip Kelly ran at UO with some power elements, guard pulling, reading LB's, etc. with maybe some option plays sprinkled in kind of like Penn State when they flip it to Barkley or McSorely keeps it.
He doesn't line up in I-Formation or anything like that. I've seen some split backs sets with 2 RB's behind the QB, and maybe some Weak-I and Strong-I elements where a WR is in there to take a sweep or something. So, Frost likes to spread the ball around and get it to his playmakers. Scott is very innovative with his offense and flexible during games.
I've seen him get aggressive with his play calling. The key is to play faster than the defense in a hurry up scheme/tempo and not allow them to lineup correctly or substitute. He takes advantage of both situations with his play calling.
