Oklahoma's defense gave up 30+ points in four of their last five Big 12 games last season. Their secondary ranked 102nd in passing yards allowed per game. Colorado's offensive skill talent is a major upgrade from most of the teams they struggled against. Shedeur Sanders will exploit those coverage issues, and the Buffs' tempo will test their conditioning. The Sooners aren't walking into a rebuild, they're facing a quarterback who threw for over 3,200 yards. This game will be a shootout, and Colorado's offense is built to win those.
