Lee Evans catch did Hurt, but if you look back it was a combination of things. Harbaugh going for it on 4th down with less than 3 minutes to go and not making it. After the defense held and the Ravens came down the field and they had 2nd down and 2 yards to go then Lee Evans dropped the ball. Then they tried a pass to Pita incomplete, then Billy Cundiff missed a FG try. The loss hurt especially since it was Brady and the Pats, but I think it led to things changing on offense, Cam Cameron leaving and the Super Bowl run of 2012.
