I'm not too judgmental of Bowles. He's a rookie head coach. It's easy to question things like going for it on 4th, but if they didn't, people would question that too. Can't please everyone. If it goes well, no one complains, even if it was a dumb decision. If it doesn't go well, everyone piles on and acts like they could do better.
I can't say I would have done anything different than he did last night. If you lose the turnover battle 4-0, you will almost certainly lose. Everything else is minor. Chan's playcalling and Bowles' decisions are all side stories in this game.
