Surprised nobody's mentioned this one yet. NFL Commissioner Roger Goodell is pushing for a longer NFL season.
Goodell wants a 17 or 18 game season, with fewer preseason games. Says the Commish: "A key point is the fans also recognize players they want to see are not in those preseason games; that’s why they are not attractive. They want to see those players play.”
Obviously, huge issues to work out with the NFLPA and the rest of the league. I doubt this gets done for the 2009 season, or even 2010. It is, however, a real possibility as part of the 2011 season, assuming Goodell avoids a strike.
(And how, you ask, does the league get a 17 game season? Easy. Each team plays one game at a neutral site, and this gives the NFL a chance to move some more games to international locations.)
