It was subtle, but it was there, and it makes sense to take advantage of. Sex sells, and everyone's buying. On TUF 20, you have a group of 16 female fighters, many of whom are pretty darn attractive on top of being able to kick your ass. The UFC is aware of this. They know guys like to see attractive girls, and they know that even a lot of girls enjoy attractive girls. It wasn't too in your face, but there were a number of shots by the pool in bikinis, butt shots, and shots of the girls posing that were no doubt included for a bit of titillation - and you know what? That's just fine, because the show and the talent of the fighters is decent enough to rise beyond just being a "lets watch hot girls fight" sort of thing. The girls all have interesting stories, and they've got excellent ability in the cage.
