Then you won't know the score if you want to go to the beginning of the game and watch from the start and it won't be ruined for you.
And if you do want to know the score, just pull out your yahoo app on your phone or something.
No it isn't. If I'm watching the games live, I want to know which games are close so I can switch to them to watch them. That way I can catch all of the intense moments, buzzer beaters, etc.
