No baseball is probably the best spot you can listen to on the radio. NBA and NHL move very fast and you have to know your players if you are listening to those games. It's much easier to follow on tv. But as far as NFL and MLB are concerned, you can easily listen to those games on the radio and be able to follow it. It's a convenience to people if they can't watch on tv. There would be a ton of Best of XM purchases though once this deal gets sealed.
Agreed. I usually listen to the radio announcer over the TV announcer when I watch the local team. Doesn't work with the sats though ... to much of a delay. But a good announcer puts you in the game even when you are in your car or wherever.
