Since the top-ranking users don't actually use football tactics and just spam a narrow selection of plays, EA should just...
1) Log what plays are called by users
2) Match winning users against winning users that call similar plays
3) Match losing users against users that actually call a variety of plays, because they're losing too
All the eBook RPO spammers can bang each other over the head, and the rest of us can play football.
Problem solved.
