Agree with above. All reports are that he's exactly as advertised. Feet and balance are allowing him to excel at pass-blocking and some lack of strength shows up in the run game. I can easily live with that in a rookie, especially considering it could be the other way around which would be bad.
First time in a few years where I feel good about the OL though I'm a little worried about Murphy so far. Concussion has held him out for a while. Hopefully the last 3 weeks of camp he comes through. Overall though, it seems we have competent back-ups at OT (Spriggs), OG (Taylor) and OC (Tretter or Linsley) for the first time in a while.
