Had we gone into OT we would have been seriously hamstrung by our O-line situation and the absence of Bell. I believe we would have needed a defensive TO resulting in either a TD or FG position to win that game (i.e miracle). The Steelers played with some serious heart. However, it was a few plays where there were failures of execution that contributed to this loss (Sushi I'm looking at you).
Looking forward, we are in serious trouble. Even if we had won this game the injury situation looks pretty dire and could put us back into another losing streak.
