No. Just... no. If Kaaya is at QB, teams would sell out to stop the pass, blitz like crazy, and gamble that the Miami run game couldn't beat them. Since our OL was basically getting manhandled all season, that's a good bet. I like Homer, but I don't think he could have carried that kind of load. Even with Walton who was a tremendous blocker, Kaaya was on his *** in most games. Early in the year, teams gambled that Rosier couldn't beat them with his arm and focused on stopping run. Rosier got some easy looks, and since teams were playing close to the line, he was able to hit deep passes. He was also able to pick up some first downs with his legs when defenses didn't assign a defender to spy him, which they didn't when in a run-stopping scheme. Kaaya could not do that. So what happened at end of season? Teams respected Rosier more and focused again on stopping the pass (see Pitt game for all the proof you need that this is true) . That meant gambling the run game couldn't beat them. And sure enough, our weak OL proved them right. Rosier's effectiveness actually became his undoing. Once defenses focused on shutting down the pass game (and we faced opponents with a stout front four that could bully the OL) , that basically slammed the door on our "explosive" offense, which was the only way that Miami scored points (again stats bear this out, we were among the worst at 3rd down conversions, meaning Miami could not sustain drives).
Long story short- teams would have been playing to stop pass from game 1 with Kaaya, and our run game would not have been able to make them pay so we likely lose to FSU and VT. At best, we'd be 8-4 with Kaaya, though I suspect we'd have finished 7-5, with losses to FSU, Pitt, VT, ND, and a bowl game loss at end (and no acc coastal win)
