Which fight are you more interested in watching?
Would you rather see a replay of Brock Lesnar versus Frank Mir or watch Gina Carano versus Cristiane "Cyborg" Santos live?

Have you ever sipped beer through a straw?
Maybe we should reword this question: "Are you male, and did you attend college?" And don't lie to us. Your mom won't see how you voted.

Who won Tuesday night's fight?
Kevin Youkilis gets points for the sprint, helmet toss and attempted tackle, but Rick Porcello took advantage of his momentum and ended up on top.

What do you think about Michigan's tackling dummies?
The Wolverines hit tackling dummies adorned with Ohio State stickers in practice. Is this a smart, motivational move or a dumb tactic?

Will the Rick Pitino story affect Louisville recruiting?
Pitino reportedly told police that he had consensual sex with and paid for an abortion for the woman who has been charged with trying to extort him.

First the good news for UFC. More than half of SportsNation knows Georges St. Pierre is, in fact, a mixed martial arts fighter who fought in UFC 100 Saturday night. Voters had until recently said hockey had a brighter professional future in the United States than mixed martial arts, but St. Pierre's name recognition is a good bit better than John Tavares' was in the hours before he became the No. 1 pick in the NHL draft.

Now the not-so-good news. SportsNation isn't sure what to make of Brock Lesnar in what should be the heavyweight's moment of glory. Lesnar retained the heavyweight crown by beating -- and then taunting, WWE style -- rival Frank Mir.

Lesnar's antics drew a rebuke from UFC president Dana White, but SportsNation blogger thechris54 thinks anyone worrying about sportsmanship should just get over it. So does this help or hurt UFC gain mainstream eyeballs?

The revolution will be televised, but will you be watching? Not so much when it comes to UFC 100 and SportsNation.

The Ultimate Fighting Championship hits the century mark this weekend in the aptly named UFC 100 (thank goodness there are no Roman numerals involved) in Las Vegas.

There's no getting around the fact that mixed martial arts are perhaps the hottest property in sports -- you don't hear Bill Simmons devoting a one-hour podcast, left, to curling ... or boxing, come to think of it. And few fan groups have more SportsNation members than MMA.

Yet a good chunk of SportsNation doesn't seem quite ready to bow to the Octagon. Two out of three think either traditional mainstay hockey or fellow up-and-comer soccer has a brighter professional future in the United States.

• Almost half of the 'Nation still not even a casual UFC fan.
• Only one in four voters will be watching UFC 100 this weekend.
