"Reserved Names" - FCS teams

I would like to play as my team, the Montana Grizzlies. Yet when I try to make it on Teambuilder, it gives me an error saying it's a "reserved name." What on earth could it be reserved for? Is EA going to make an FCS team DLC? If not, stop holding me back from making my team. 

And I'm not paying $10/month or whatever it is for Xbox Live just to play with a team called the UMT Grizzlies. If I'm paying any more than sticker price, it better be downright perfect.
