As much as we all dislike Harbaugh, we can all agree he's a great coach. Without him making the 49ers the powerhouse they were, I doubt the Seahawks would be as good as they are. Even coach Carroll said that (according to Aikman during the game) Harbuagh also made the Seahawks a better team.
Without that one team we were trying to chase, I doubt we have the arms race to go out and get Avril, Bennet, Harvin and others to build our Superbowl team, IMO
