I would think you would have the 75 man roster before your first season. If the season starts sometime soon the rosters will balloon up to 75 players pretty quick and I'm assuming they'd be able to get those rosters on to Madden before shipping. This sure would be the ideal situation to have your Madden roster battle while the real NFL is going through preseason. Hopefully the NFL gets it's stuff together so I can enjoy real NFL with my Madden
