Not really a prominent area of strength for any of these teams.
With a healthy Peters, I think I like the Eagles the most. In any case, it's tough to evaluate them because of the way Vick plays. Their interior linemen were, believe it or not, not really better than ours last year. They get good push but they were awful picking up run blitzes - McCoy took a lot of pretty big losses. They're excited about King Dunlap (I don't know why...), but Peters is one of the best. Pretty big loss.
New York's isn't very good either. I think they'll improve the most year-on-year by getting rid of McKenzie, who was an utter disaster. Inside, Diehl and Snee are OK - Snee isn't what he used to be. Baas is also just OK.
Washington is a confusing mess. They rotated through a ton of people last year (not too dissimilar from us). Trent Williams is a nice tackle, and the rest are journeyman system blockers. Little zone guys all around.
Here's where I'd put them...but it is a complete mess all around:
Pass Protection:
1. NYG
2. DAL
3. WAS
4. PHI (without Peters)
Run Blocking:
1. PHI
2. WAS
3. DAL
4. NYG
