MYKL also told me about a website with some concept art. The website is http://www.ssur.org/.
This first picture is a set of concept art.
I really like the jerseys but the actual logo doesn't look as good as the current logo.
This next logo is a cross between the current Cardinals flag and the Arizona Flag.
It looks better then you would think it would.
This last picture is a new uniform and helmet. Yellow is now a major part of the uniform. I think most people would like these uniforms if they saw them on a player.
