I'm with ober. I can understand watching live I you're interacting with others while the game is on (duh!), but otherwise I only watch games live from the start if I'm already watching tv when it comes on. Also, I'll watch some games a day later, depending on how important it is to me. I prefer to see things myself rather than read about them or watch highlights.
The kids thing is the biggest. I have so little time to watch my stuff that if I want to see something like the BCS title game I just record and fast forward through it in an hour. I can't justify three hours for a college football game between teams I don't care about when dishes need to be done, babies need to be washed and there are 15 to-dos on my list.
