Middleton is the guy that intrigues me. He's a big wide body and has been a very good guard for awhile. He battled a quad injury all last year and will likely be a cap casualty.
I'd like to see Whitley get a shot. But Middleton could certainly solidfy the interior.
Kenyatta Walker is a total bust. Remember, they also traded up nine spots in the 1st to get him. Total waste of time. He's backup material at best IMO. Bob Whitfield was said to be pretty bad last year too. I the games I saw him in, he was horrible.
I like what we've got at LB. I'm confident in those guys. Trotter won't fit in here either. I've got no interest in him. Terrell hasn't done much either. It's hard to get excited about guys who have disappointed.
