In Madden 15 (Xbox One), you could go to Manage Game under 'My Games and Apps' and delete the small reserve data to the right of the game data itself. It's the 5kb-25kb of saved info for your account. When it asks to delete for your xbox or everywhere, choose 'Delete Everywhere'. In Madden 15 I restarted my MUT 3 or 4 times, I haven't tried in 16 though.
