It is very hard to win any football game when you lose the turnover battle 0-4. An interception that set the Bucs up at the Saints 3 yard line, a costly fumble by Jared Cook that completely turned momentum, and two interceptions on the last two drives of the game, absolutely devastated the Saints chances to win.
The 21 points the Bucs scored off turnovers were clearly the difference in this game, and we can only wonder what would of happened had Jared Cook not fumbled when the Saints were up 7 and driving.
