I agree with bigtplaystew. I love the smaller weight classes and I think they put on exciting, action filled fights but I don't think Mighty Mouse is the guy that's going to draw new fans in just to see him fight. I think if McCall would have won that first Flyweight tounament like he should have (imo) then he would be a better draw because who doesn't want to tune in and see a guy called Uncle Creepy fight? But who knows.
I think for now the UFC is making a wise decision by putting the Flyweight title fight on the TUF 17 finale instead of PPV because this is one of the most hyped seasons in years and there should be a good amount of anticipation going into the finale, especially if Uriah Hall makes it to the finals so you'd have to think that there will be a good amount of viewership ranging from the hardcore fans to people who have never even seen the UFC. Eventually I think they'll start putting the Flyweights on UFC On Fox and then after that PPV unless they get the injury bug again then they would have to throw them on PPV sooner.
