I'd be interested in that, but as I understand it they black out your home games; so I'd still have to watch them on cable anyway without the whiz-bang features. I'd guess most people are like me and are fans of the team in their market.
They blackout your home games and all nationally televised games (although there may be a carrier-exclusive deal worked out here and there).
It's a shame that the NHL signed such a long deal with NBC. I know it was just a couple years ago, but everything was so different then. I hope when their next deal comes around, the NHL is the first to abandon these stupid blackout restrictions.
Besides, if you stream it live, you're still watching the commercials.
