What happened to Karo?

Early on in his career, Karo Parisyan was considered one of UFC's most highly touted fighters.

In his UFC 94 fight, Karo appears out of shape and gassed, and it's showing in his performance.
In observance of the Dong Hyun Kim versus Karo fight, I actually thought Karo was out fought the entire match.

Ever since his loss to Diego Sanchez, Karo's never looked the same; he put up a great fight, but reaching such a high and still losing in a close bout must have put a dent in his confidence. I love Karo's skill set, hes a very well rounded fighter. His judo throws and ability to get out of sticky submissions places him as one of the best Jiu Jitsu fighters, but he severely needs to work on his striking; versus Dong Hyun, Karo's striking was inadequate.

Don Hyun had his back for most of the match but never truly capitalized, he still managed to hit Karo more and attempt more submissions on the ground, which makes it hard to believe Karo should have won; this was purely on a name basis and it being Don Hyun's third fight in the UFC with not much name value whatsoever.
