I have heather green UNT shirts, a pink one and several white ones (in addition to all kinds of green ones). I actually have more UNT shirts and gear than I have for my alma mater of Baylor (who's going to a Bowl game this year *doing the dance of love*). So, I think showing the Mean Green love can come in all colors. If I have my choice, I'll wear my green shirts, but my heather grey NCAA tourney UNT shirt is pretty awesome. Plus, I got my pink one (with green logo) for the breast cancer awareness stuff.
*shrug*
I think if this is the only thing we have to grump about, then we're doing pretty good.
And, let me quantify all of this by saying, I don't like the black either.
