Taken from the blog of Anthony Whit, game designer for EA Tiburon:

The team playbooks in Madden NFL 09 have undergone a major overhaul.  As many of you are aware, each week during the NFL season we receive the actual coach’s film of every game that was played in the NFL the previous week.  I personally watched and broke down game film on every team in the NFL and we’ll show you a few video clips of plays that were created as a direct result of film study.  With the large number of hours devoted to studying film the end result was the addition of 31 new formations and over 1,200 new plays to this year’s Madden NFL game.

In this year’s edition of Madden NFL you’ll notice new schemes, new terminology, and a more streamlined organization of the plays within each playbook.   All 32 team playbooks are now much more unique and authentic to their real life counterpart’s style of play.  Whether it’s the Patriots heavy use of the shotgun spread offense, the Seahawks west coast system, or the Bears power run game, you’ll see that reflected in that team’s playbook.  It also comes to light when playing against any of the CPU controlled teams in a Franchise or Play Now game.  We made a concerted effort to tune each team’s playcall logic so that it closely mimics its real life counterpart’s style of play.  That means when you play a team like the Patriots they’ll use lots of shotgun, the Steelers and their use of bunch/condensed formations or Packers with their Full House backfield package will be evident.

Offseason coaching changes were also taken into consideration when building our team playbooks.  New coaching staffs in place for teams such as the Falcons, Ravens, Dolphins, and Redskins were all taken into account.  Offensive coordinator changes such as the ones that took place in San Francisco, St. Louis, and Detroit were also factored in.
