By my count, we averaged 4.4 yards per rush, with Lucky averaging 4.9. It's not great, but it could have been better had we had time to establish the run and pound their defense into submission. Okay, the worst grade you can give the running game is an incomplete and say the jury's still out. It could have been worse. If those backs played like our defense....although it could have been better, I think you consider the unusual circumstances and reserve judgment.
By the way, the 3.2 ypc figure is arrived at by including Keller's 5 rushes for -19 yards. If you want to say that, then Keller never got sacked. I believe three of those were sacks, one was a fumble he got back, and one was a broken play...I'd say the two non-sacks should be part of the rushing game, but all the same, that's still over 4 yards a carry. It's not awful, again, circumstances allowing...
We can all agree Lucky had mostly a heck of a game, and our O-line run blocking left some to be desired.
