I don't have the actual PFF stats to post, but according to a redditor (Iamostrich) over on /r/panthers PFF has him graded as the 6th best guard in the league. Oh, Gross and Kalil are doing pretty nice too.
He's also 4th in run blocking and he's played 1 fewer game than everyone else in the top 10. Pretty impressive, seems like he's really coming along.
Also, Gross is the 8th highest graded tackle and Kalil is their 4th highest rated center. The left side of our line is looking like one of the best in the league right now. Sadly Byron Bell is the 43rd rated tackle (better than last year though) and Chris Scott, who's started about 85% of our snaps at RG, is the 5th worst guard right now...maybe it's time to start Byers and/or Wharton on the right side? They can't be worse.
All I can say is
In a pleasantly surprised kind of way of course....
Didn't see that coming.
