Make him choose. Decide (together!) that a dad with little kids can no longer watch college and pro, and must limit himself to one game per day.
Mute the commercials. Yeah, some of them are fun, but lots -- for beer, erectile-dysfunction pills, horror movies -- may be less than appropriate for kids.
Divvy up child chasing. If you're both fans, you do vigilance and diapers first quarter, he does it during the second, and so on. That way, you both can enjoy the game.
Leave him alone (with your children, that is). Go for coffee, hit the mall, head to the gym, and let Mr. Sofa-pants deal with the kids. They'll be fine.
