He's 3-0 in MMA and hasn't fought in the big leagues. I appreciate the fact that many people think he's a legit prospect, but as of right now, he's untested in MMA, and so I'm not sure why he gets so much media coverage.
It's one thing if every prospect got airtime / exposure from UFC (and the media who seems beholden to them). But UFC seems to follow a pattern where they hope to catch lightning in a bottle and so they pick a dude they like (Greg Hardy, Sage Northcutt, Paddy, Till, now Rosas) and keep giving them the spotlight despite repeated underwhelming performances. When they finally wash out of the UFC, Dana & Co just move on to the next thing.
The reason this is a problem is two-fold:
1) It comes at the expense of legit prospects/contenders who don't get the exposure they have earned, resulting in them being virtually unknown to the casual fan, which in turn costs them title shots, and keeps them unknown in the prime of their careers.
2) Hoping to catch lighting in a bottle is an outdated way of doing talent scouting - it's like the old baseball scouts saying "I have a hunch about this guy" instead of actually using metrics, considering strength of schedule, etc.
