"The Steelers rank 28th in points per game (16.6), 28th in offensive yards per game (280.1), and 31st in passing yards per game (170) this season. "
These are actually better rankings than Tiny D Jack’s defensive unit, which is 32nd (dead last) in both overall Points Allowed and Points Per Game. Yet he still has his job at the time of this posting. Why? Could someone else honestly do any worse with this defense for the rest of the season?
Rivera is a defensive head coach. If you want to blame someone for an awful defense, blame him, it’s his scheme and his players.
