Don't know the extent of which this has been discussed, but the offensive line has only given up 4 sacks this season, which is 3rd best in the league. Given the few injuries and shifts the team has had to make on the OL, they are playing extremely well. It's not only in pass blocking, but the run blocking has been noticeably better than last season thus far.
It's not exactly the weakness that most people thought it would be.
Now only if those damn pass rushers could get to the QB on defense...
