Keenum is not going to take Denver far.
Part of the problem is their Defensive coaching. I couldn't believe how they chose to defend the Chiefs in the last half of the 4th quarter. It was dumb to constantly go man when zone would have not allowed 20 + yard completions. It reminds me a bit of Indy's Reich going for it on 4th and 4 on their side of the 50 with 24 seconds left in a tied game. Not very smart.
Denver played about as well as they could, at home, and still lost. Denver, to me, is no better than Cincy.
