No, they played tough enough defense to keep the game close. Then Tebow managed to conduct two or three decent drives after he and the rest of the offense stunk out the joint. They made the playoffs, because the Raiders and Chargers played as if they did not want to make the playoffs. If McCoy were the defensive coordinator, I would give him props. That option foolishness did not do squat in the playoffs when New England figured it out. That is like saying that Dan Henning was a good coach, because he used the wildcat.
Mr.Day hits it perfectly. In watching most of their games this year, it was their defense that kept them in it. The offense all season struggled to get few or any points all game and if the defense kept them close enough by the end of the 4th quarter, teams played just conservative enough to lose to them on one or two plays (like we did). That was why they were successful. The offense played conservative and struggled all game, while the defense usually kept them close enough for Tebow to make 1-2 plays at the end of the game. How that makes a great OC, I have no idea.
