There's good news at the NFL Network. Bryant Gumbel is moving on and won't be doing any more games.
I don't think he really cared about doing the games. It doesn't seem like he really likes football. Gumbel seems to be bitter. You don't see to many smiles when he's calling a game. He also hasn't kept up with the sport intensively since he left the sportscaster business years ago.
That's not exactly a characteristic of a play by play guy. If he doesn't enjoy the game then why would you think the audience would like listening to him.
Now that they've got that worked out, they can work things out with Comcast.
