He's fun to watch, but he's fairly one dimensional. He's defeated a few big fighters but he's nowhere near well rounded enough to compete with the top fighters. His roundhouse is his main weapon. He's obviously in good shape and strong which always helps. I tend to think that if he got in the ring with the best of the best (Arlovski, Fedor, Wanderlei Silva, etc..) he's get stomped, but you never know. It sure is fun watching him kick people in the head.
