Joe Flacco didn't lose the game for us today. The team lost the game. The defense couldn't stop Dak and the Cowboys once in the second half and after those first four punts, I think I saw that they didn't stop them again? You can't win the game if the defense doesn't stop the opposing offense once in the second half.
The offense was moving the ball, until we had those penalties. Also, the offense barely touched the ball in the second half. Dallas controlled the time of possession overwhelmingly in the second half.
Joe Flacco was 4/7 for 75 yards and a TD with 7 or 8 minutes left in the game. The defense never stopped Dak and we got the ball back with less than 2 mins down 2 scores. Joe did miss some easy throws but on a whole, this was a team loss. He didn't lose the game for the Ravens today. The whole team did. Last time I checked, football was still a team sport.
