The whole Euro league lost almost $20 million a year, that's lass than what Joe Flacco makes in a year, from a player development aspect, each NFL team can pony up $625,000 in my opinion, not to mention airing it in the US, the NFL can really tap into the spring/early summer TV market, especially with the NFL network as another poster mentioned. I say bring it back.
Make 8 teams, one made up of all AFC East, West, North, South and NFC East, West, North, South.
