There's a new glitch out there that makes you lose a win.. example i won a game, went to check my record the win was there but it did not show my opponents gamertag... I was still +1 in wins but the gamertag of my previous opponenet was still atop my list. about 2 minutes later suddenly i was -1 win like the game never happened.
His gametag was SalOz3 or something like that.
I did some research i ended up finding a website selling it... this is truly the end of Madden 10 ranked games.. oh well
