Why is there a narrative that the OLine is horrible?

7 out of the 15 sacks are per both PFF and other analysts on Burrow. The run game issues are part Mixon being hesitant and a step slow AND problematic run play design. Notice that once they put Perine in AND stopped trying to run stretch plays and instead went to the RG-RT gap all of a sudden they were moving the ball well against a defense that knew the run was coming.
