"'Any Given Sunday' isn't just the title of a bad football movie; it's an old adage that you never know what you're going to get when players step out on the field. Anything can happen. Your star QB could sling it five yards past every receiver. Your shaky rookie cornerback might come up clutch with a game-changing interception. Over the course of weeks and seasons, players are defined by their tendencies and begin assuming roles in their teams.
Madden NFL 12 developer Tiburon recognizes this and has made it part of the core upgrade to Franchise mode. It's true, Madden has disappointed with its Franchise mode the past few years, but that looks to be changing this year. The amount of improvements is staggering, but the most significant are the additions of dynamic player performance and player roles."
IGN will be releasing a follow-up blog on Monday, May 16th going more in depth about the changes to Franchise Mode.
