i think there should be ....
*DogPiles on the goal line or stuffed on 3 and inches or something.
*New catching ( if you miss sometimes it looks incredibly unrealistic)
*New tackles ( I want like 30 things depending on the situation and how your getting hit, like behind or side or infront and how many people ... to be different)
*Madden To say new stuff...
*People in Franchise Mode to be like a T.O.
*Better Fan Animations make the fans look semi real also have like people selling cotton candy or pop or beers in the stands.
*New Celebrations (including Traditional celebrations like the Lambo Leap. Or Mile High Salute if not already included.)
*Sidelines/players on the bench , look more real
*Different Hitstick And Truckstick animations ( different movements of just laying someone out.
*Coaches Look More Real and detailed.

Well Thats all the ideas i got for now.. bye
