CBS analyst Shannon Sharpe, a former NFL tight end, believes that Brett Favre will keep the Jets from winning the AFC East title this season. "How often can you say Brett Favre, during the course of a game, is not going to put the ball in harm's way at least once?" Sharpe said Sunday on CBS. "Do we expect Brett Favre, over the next six, seven weeks to play as flawless like he did Thursday night (against New England)? I don't believe he can."
