Yeah, I'd have to agree with BN. I wouldn't hate a CB pick, but I think it would be a big mistake.
My thought is that in a Zimmer defense, ALL corners are developmental players, so why not wait and take a developmental corner? Plenty in the middle rounds. We're so close, take someone who's going to help us right away. Someone who can help protect our 84M investment, make our receivers better, make our back better. And it's not like there's no value at OL at 30. That's exactly where the value is!
It seems pretty obvious to me...but we'll see.
