First of all, everybody at the bar was cheering for "the cowboy" last night. People know who he is, and everybody where I was at was aware who he was and was pretty firmly behind him. Dude is a fan favorite. If he would not have adrenaline dumped vs Nate because of how he started in that fight, he would be on one of the best 5 year stretches at LW ever, and that includes losses to two of the top 3 guys right now.
Anyways, he's popular because he fights a lot. Also because he has some cool finishes, but even more so because he fights a lot. The UFC should take notice that part of building a star is making them seen doing what they do. Pride made stars with hardly any "promotion," but just from guys being in tournaments and staying active, even against lessor competition. I don't see why guys always have to fight a guy ranked right next to them when there are 80 guy with a decent record within a division. Keep guys busy, that as much as anything is what makes them stars. Cowboy, for a smaller weight class, is officially a star.
