The ability to run behind this Two TE offense is going to really help the OL. Their predictability the second half of lat season put them at a serious disadvantage and put Brady under intense pressure the rest of the season, the Two TE offenses and Jumbo packages they can put out this season should help remedy that problem. They are going to be able to, throw the ball effectively out of their Jumbo, packages and that's going to be a nightmare for opposing defenses.
I can actually see a scenario, where Williams comes in as an extra Tackle and they split Gronk and Bennett out with either Lewis or a Blount in the backfield and Edelman in the slot. Good luck stopping that.
