Great Football Theme! Rated 5 out of 5 stars
Actually I'm only a football fan every two years when an int. championship happens, but that's another topic. ;)
I think you've done a great job with that theme. It has nice coloring and icons, and foremost it's really complete and consistent. Tested it on WinXP and FF3 and had no problems.
Only two small criticisms: I think it's not nice that the Options background is repeating itself so often. Maybe a wider color gradient would be better there. And the buttons look great, but maybe you should also add a hover and active effect to them.
