I have a team nearby me, the Sacramento Mountain Lions, but I don't support them (no hate against the team, just hate Sacramento in general). The team I follow is the Omaha Nighthawks, have similar colors to the Raiders, a pretty good logo, and best of all a rabid fanbase. I'm hoping that fanbase will still be there as they move into their second year in the league.
The UFL bled a ton of $ its first two seasons, and they'll definitely lose some more in the third, but I'm hoping they find a way to stick around. If they can get a better TV deal than the one they had with Versus, and get a few more teams for their fourth season, they should be able to do well in the future.
I remember reading their biggest target cities for next year are Portland, Salt Lake City, San Antonio, & Los Angeles. San Antonio was supposed to be the 5th team instead of the Omaha Nighthawks, but talks broke down back then. I head over to the
UFL Access forums to stay up to date, and last time I was there I remember reading talks with San Antonio had resumed.
