Well, the offensive play-calling was varied and imaginative -- the passes were very widely distributed and the runs themselves also nicely inter-spaced. Last week there seemed to be a pattern: start with a run on first down, not make much yardage, have a pass dropped on second, then heave and hope. As for the defense, getting what seemed to be, in effect, coverage sacks from a secondary missing two starters out of four is a pretty good achievement. Add my impression that, overall, the Bengals didn't have a good idea of what was coming. So my guess is that it was a very well coached game.
But it can't be much more than a guess from watching it on TV: it was a very difficult game to assess since CBS gave so very few replays from broader angles.
