The most important aspect of this competition is to incorporate a financial theme. Sports is in the name, so I'm not sure it needs to be emphasized too heavily in the logo. The idea is to insert a financial theme, but please bee subtle. A really nice example of subtlety is the logo for Mint.com, which I have included. See how the dollar sign has been integrated into one of the leaves. This is an excellent logo.
Please do not incorporate the imagery from a single sport like American football into the logo. Also, I am not looking for a generic "S" icon.
I typically like it when the image conveys 3d depth and is metallic or glass like, but this is not absolutely critical. I also like for the colors to be brighter and I like gradients.
The logo needs to be displayable over both a dark background and a light one. We will also need a version that can be stitched into hats and shirts, etc.
Lastly, there is a strong possibility that we will want to retain the winner for further work in the near future.
