I love the colors and how he's blended into the background and the motion like thing you have going in the sig. However, I'd add a border that's more distinct maybe white or something like that. I can't exactly tell if there's a border. As for the text, something more modern/techish is good but text isn't that great. I'm not good either so yeah...
I suggest also making the the Portis render easier to see cuz it looks a bit blurry to me. Otherwise,
New England Patriots :: 12-4
New Orleans Saints :: 10-6
