I can't say that I watched the line that closely. I do believe that overall, they did a decent job. But as many have stated, Fitz made them look better than they were. He sure did. He made quick decisions, released the ball quickly and scrambled well. In the 2nd half, he took some hits just as he threw after only having 2 or 3 seconds to make a decision.
To drive this point home, my wife was casually watching the game (she doesn't watch much football). She said "man, it seems like he throws the ball really fast". She wasn't commenting on his velocity, but on how quickly he got the ball out of his hands. I hope the o-line continues to improve, but for now, Fitz is helping them along the way.
