On the cheerleader side of things, it's a pretty tough call. Let's check out the evidence.
NEW ORLEANS SAINTS
The Saints girls just look like they know how to have a good time. Probably the fact that they live in New Orleans and are smokin' hot. I think those 2 factors alone automatically make a girl look like she'd be fun to hang out with. My guess is these girls rule Bourbon Street.
SAN FRANCISCO 49ERS
There really is something to be said for cheerleader outfits that make the girls look like pirate wenches. I'm not into pirates as much as some people, but the pirate wench look is a definitely a winner
I think I have to go with the Saints on this one if for no other reason than the adorable little blonde in the last 2 pics. She puts them in the lead against just about every other team in the league, in my opinion.
