The only graphical problems are with the QBs everyone else in this screen looks fine. For some reason the Mannings both have that painted on helmet look and somehow Eli found a football from Madden 11 in this shot. EA is a crazy place sometimes.
I just played some Madden 10 and it was better than this in terms of look. The jersey numbers were smaller and elis face looked more like him and his helmet wasnt tiny. Something happened from M10 to 11 where correct looking uniforms went very wrong.
He looks fine to me, forget to mention they are brothers and do look rather similar
The only reason he looks like peyton is his expression on his face in the game during the snap. He does have a spacely look to him and mellow relaxed face. As others have mentions a "lucid cow" look. Madden seems to give him a courageous competitor look like he is some general but overall he is fine
This looks more like that guy
