Harbaugh's not talking to each other

Yes. Beerpong.

Do you honestly think there are stretches during the season when they don't speak for more than 4 days?

This is different, for obvious reasons. If you can't see the difference, then I don't know what to tell you.

These two men that have grown up together and are in the same profession just engaged in a Super Bowl. I would think a congratulatory call would be in order. Even if they shook hands after the game, I would still think that the two men would enjoy a private moment together in the days following. I would think he'd call him even just to poke fun at him: "you know you got lucky right?"
