I think espn wins so far in this pole b/c many ppl don't get nfl network.
NFL Network wins in every way you can consider by defaut, other than perhaps commentary or maybe graphics. They get the direct lines to all information (ie. first word on everything other than rumor), have first choice of camera locations, have the most access to everyone in the league (including camera crews in war rooms), and have a say in how the events go down so that they fit their channel.
Of course NFL Network.
