Rock-Em-Sock-Em-Muttonchops was not only a real action fighter, but a genuine rankable talent with a lot of upside. He had some difficulty adjusting to lighweight and racked up a number of losses since his debut, but after he moved to welterweight, he has 7 fights where he only lost to #12 Maia and "lost" to Neil Magny
I believe he left for free agency after that. I always marked him as a guy who could just start a run tomorrow if he wanted, but it seemed like he never was going to make it back to the UFC
