I think the call is somewhat debatable, though I lean strongly toward going for it on 4th and 2. As others have said, doubtful that you are going to get the ball 2x in that short time frame.
But more interesting to me is the dramatic change in Marrone's approach to 4th down. How many times has he gone for it on 4th down in the past few games in situations where earlier in the season he was punting without hesitation? And then defending the decisions in strong words at the podium after the game? He has changed how he approaches these critical situations. And for the better, for the most part.
On the one hand it's good that he saw the error of his ways. On the other, it's bad that he had to have that error pointed out to him.
