You rarely see games like this were one team (BYU) is a seven point favorite, yet most prediction computers call it a wash. I'd take BYU to cover the 7 point spread assuming Mangum stays healthy and Kiel isn't 100%. Cincy's defense has been porous against the run and even more so against the pass.
If Keil plays and is healthy it would make a big difference. Assuming he doesn't, BYU has a way of showing multiple looks and making younger QBs become confused. Teams then typically have to rely on the ground game. With Tuiloma back and Cincy's propensity to throw, we should see more screens and quick throws, which is BYUs weakness on D.
Assuming Davis is ready to go, our secondary will be healthy and complete and although we'll give up yards in the air, we should create several turnovers to even it out.
I suspect Anae will have a conservative playbook, but based on Cincy's defense that will be the best approach. Throw the bomb happy Mangum into that approach and we'll still be looking at some big plays to counter the HB dives.
As long as we're ready and show up, I think we've got this one. You never know until they start to play, which is what makes the game so exciting!
