How much reworking per year do these sports games really take? I mean...I can pick up and play a new FIFA or Madden game after not playing one for several years and not really miss a beat but for some slight tweak to get used to. They could easily just release one game every five years and only offer roster updates and possibly new commentary as DLC for players who really want them. Personally, not being a big fan of playing multiplayer and more of a career/franchise mode player, it wouldn't really bother me much.
