We've had problems with strong pass rush teams, Giants, Ravens. Pats might need to assign guard help to the outside leaving the dreaded interior rush blitz open.
I felt like the Patriots OL did a good job against both the Ravens and Giants in the play-off's this year. They struggled in those games but I never felt like the OL was the problem. The additions of Solder and Waters last year with Gallery this offseason really improved the line imo.
