To get the teams sugerbuzz, the monsters, the mummys, and all those other teams. you have to have more than one EAsport game.
Whenever you play a game your xbox will save the game in the xbox.
so when you save an EAsport game the xbox programs the brand EAsports in the memory. so lets say if you had Maddan2004 and you save the game.
Then you take out the game and put in Maddan2003. you will have the mummys and the other unbeatable teams.
