I've thought for a while now that the NFL network - their TV presence, the website - is the future of how sports will be. It's an incredibly good product if you're a football fan (as I am - go Niners).
The TV channel is well done for the fan, a mix of informality with information - bunch of faces that make us nostalgic due to their past achievements combined with solid anchors who have personality but don't try to outshine the hall-of-famers who know their stuff.
The website is very well done, interactive, some fun game dynamics. Their apps are good enough - much room for growth but they're getting better.
The all-22 game tape is a nice step forward here.
I think people who want to study the future of pro-sports media in the evolving media marketplace could do a lot worse than watching what the NFL is doing.
