Fair enough evaluation. There is this idea that OU has a lot of experience, but that's really only in the trenches (which is important). The rest of the skill players are mostly freshmen and sophmores who are just really good. But getting owned in the trenches will make the other positions look even better.
I dont think WR talent alone would be the reason why you dont get blown out. Ttech had crabtree when they got blown out 65-21. OU's strength has been against the pass, leading a pass happy big 12 in pass D for the past couple years. So that ought to make for an interesting side story.
For OU on offense your biggest concern might be the run game. With massive and a deep Oline and 3 big strong and fast running backs, i wouldnt be surprised to see them put 230+ on the ground. Blake Bell man, that ex qb we are only discovering what impact he'll have. I bet he scores a td. and of course shepherd, you'll hear his name a lot. On defense, its the front 7 hands down. they are fast, they are everywhere, and they're pretty big. Watching them play this year will be a real treat. If your receivers are good enough to make life hard on OU's cbs then i'll be impressed . Big 12 passes a lot so I am sure they'll be up for the challenge.
