They didn't convert third downs all day long.
They converted 9 of 18. Our defense got enough stops to win the game, despite such "poor" tackling, and as the article astutely points out, we seemed to fold up on defense after the offense kept putting them back on the field and the snap count got so out of hand against them.
Frankly, we were not healthy enough at LB, despite the guys being back, and Auburn exploited that wonderfully. Give them credit.
We did not exploit their weaknesses on defense well enough, and I'll agree that's on the coaches. But I don't think we're in as bad of shape as everyone else seems to. If we can catch a couple of breaks this weekend and get into the playoff and get healed up, I like our chances as good or better than any other team out there.
