I think that Wade and Wiegert make a good right side of the line. They are average pass blockers but good run blockers (although Wade is the better pass-blocker of the two). I don't think Wand and Pitts have enough experience in their positions to be fully graded yet. I think when Pitts gets experience, he will be an average pass blocker and good run blocker too. I would expect Wand to eventually be the best pass-blocker on the line.
McKinney IMO is a weak link. He gets manhandled and really doesn't have the potential to get any better. I'd like to see us draft or sign a C to compete with him next year. At the very least, I'd like us to begin to groom his replacement.
