OU is not going to play 10+ guys consistently on the Dline this year. That is crazy. Bonnito, Thomas, Redmond, and Winfrey are going to take most of the important snaps. There are a few guys that will get snaps to relieve those guys (a few options at rush, Ellison, Stokes, and probably Kelley/Coe). Anybody that plays after that is going to be playing mop up. You don't go three-deep and play lesser players when you are chasing a title.
And they will replace the Dline starters. Bonnito, Thomas, Winfrey, and Redmond are all projected to leave after this year. Something could change, but I'd be shocked if anybody but possibly Redmond was back next year. Who behind those 4 has accomplished anything on the field yet that resembles replacing what those guys have already done?
It's silly that we're even having this discussion. It's literally the biggest talent gap we have from starters to reserves currently.
