Realistically does the players on the offensive side of the ball match up with what Frost game plans. He can adjust, but I would imagine he will try to make his gameplan as similar as in his successful past. UCF recruited in the past for time possession gameplan, slowly grinding up and down the field. Unless there is some JUCO pick ups, seems hard to see the players transitioning to a whole new gameplan in 1 year. At least a few players are going to have to somehow learn how to be fast, cause there were at least a few that looked incredibly slow as oppose to who ever the opposition was.
Most coaches usually do not make significant progress until their recruits are in place, and that's not even in situations where the two coaching strategies are completely opposite.
