As you say Tony, I can't figure out how anyone could be anything but ecstatic about the play of the OL this year compared to last year. Let's compare: at LT Soldier is back and playing great (IMHO if he hadn't been injured last year the Pats would have a 5th ring); Thuney has stabilized the LG position and is a revelation; Andrews has made a second year jump and is bigger and stronger; Mason/Karras are at least stabilizing run blocking; and Cannon is IMHO clearly playing better than last year for whatever reason. They have played well against three of the best DL's in the NFL. What is not to like?
Moreover, and this is an important point, they have done well without Brady at QB. Beyond being the GOAT (which I think is now generally accepted) and still the best QB in the game (which I think is clear, some don't agree), I have always been of the mind that the best offensive lineman the Patriots have is Brady. That is, his ability to read the defense, make the calls, and get the ball out fast makes the OL look better than it is. However, the OL has looked really good with JimmyG and Brisket. Is the improvement 100% due to improvements in personnel and the return of Scar? Or, is having a QB who is a running threat a factor in this improvement also? It will be really, really interesting to see how the OL performs when Brady returns.
