This is the play of the game to me--not because it's the most highlight-worthy, but it tells the story of the game to me more than any other. It's offense, but the entire line getting together in a scrum to make 13 yards on 3rd down was really important to the game (hopefully, the time code for YouTube works--if it doesn't, go to 17:14 on the time slider):
If you look at the stats, Dontae is our most effective runner up until yesterday's game. If you look at the matchup yesterday, Pitt is tough against the kind of running that Dontae is best at. Third and goal from the 1 and 4th and goal from the 1 told that story (and, in retrospect, I'd have preferred different play calls against Pitt's defense)
Hall is normally our least effective runner, but he was the right choice against Pittsburgh--his speed made him dangerous. Against a speedy defense, Smith might be a better choice.
