There are times when the Patriots convert on third down, or force a third down stop, and the officials throw a flag to negate a good play and swing the momentum in the favor of the other team.
One example was when cornerback Leonard Johnson was flagged for defensive holding on a 3rd and 8 on the Tennessee 22 yard line. Cornerback Malcolm Butler had intercepted the ball, but the replay showed Johnson utilizing a full DDT on the receiver. The Titans received an automatic first down off of the 5-yard penalty.
