Either
a) You know nothing about football or
b) you didn't watch that replay
There is NO way you could've watched that replay and figured that the offensive line was doing a quality job. None. They were AWFUL. Receivers were still jogging routes and not making any attempt to get separation (any receiver not named Lenz was guilty of this multiple times).
What, specifically, did the OL do (or fail to do) that made their performance awful?
