Name Team, Win T-Shirt

Now that we have some t-shirts to give away as a prize (what, free posts don't count as prizes anymore?), it's time for STF's first ever give-away contest. The contest will also answer a questions that has been proposed in many an email....

"What team is that in your logo?"

If you can name the team in above logo, you've got yourself a free t-shirt. First person to answer it correctly wins. Feel free to answer in the comments or via email. We'll start dropping hints if we don't have a winner after awhile. This thing rides until we have a winner...

HINT #1: Took place this decade.......

HINT #2: West of the Mississippi...

Guess as many times as you like, limit one team per comment/email. If you don't hear back, that means your guess is incorrect.
