Madden-School has released every Madden 11 playbook on Offense.  Some of the highlights for Madden 11 seem to be Green Bay, Dallas, Atlanta, Denver, Houston, and New England.  We will let you decide for yourself.  We have uploaded all 38 offensive playbooks to our youtube channel.

From my initial impression, my guess is 3% new formations and 15% new plays.  Not as much change as I would hope for, but it is better than nothing.  Some new formations include Singleback Flip Trips, and Bronco Heavy. Be ready for Madden 11 the day it drops.  Choose your playbook before it comes out.  To see every offensive playbook in Madden 11 check out our YouTube channel.
