Carew did have a slight knee "injury" but he is just fine and will be ready to go. Having him in the lineup will be very big for this team and hopefully he can stay healthy. He is a huge talent for sure.
I agree that Okie State probably poses the biggest threat right now but I think that PSU and Minnesota could cause problems and challenge for the title as well. There are just a lot of questions around PSU right now with Long, Sherlock, and Ruth having legal troubles and redshirt questions with Alton and McIntosh. It will be interesting to see how there lineup will shake up.
