There is no doubt that the interior of the Patriots’ offensive line has been the weak spot of the offense in 2013. Center Ryan Wendell and right guard Dan Connolly (-6.6) have both regressed since 2012. Wendell’s -9.1 pass blocking grade is the second worst of any center, though he seems to have improved his once excellent run blocking in recent weeks. Both of these players will need to bring their ‘A’ game this week against JJ Watt, who may be the best player in the NFL.
