Maybe it is expectation, but I remember seeing his guy get to the QB often this season. He has regressed in my opinion, not an insult still a HOF player but honestly I would rather see him moved inside to Guard if he is going to be back next year. He just doesnt have the same ability to hold off outside rushers he once had, he is still faster than he seems like he should be but quick movements seem to really defeat him now too often.
Not really important to my point, which was that the OL was able to absorb the loss of Peters because it was a team strength. The other 4 OL have been playing at a high level, with 3 of them being reasonable to show up at the Pro Bowl in my opinion, so losing Peters, while Vaitai is a drop off, was not that bad.
