Definitely KW's fumbles against the Giants. But, I finally got up the nerve to watch that game again the other day. While KW was playing recklessly throughout the game (fumbled on attempted reverse, dove for a punt and managed to catch it), I have to say the game was lost by the offense and their inability to move the ball through the air. They had ample opportunities, ample, to win that game. It was there, they couldn't grab it. In the second year of the offense, with better WRs, hopefully that issue has been ameliorated.
