Del Rosario (rip) was an ace and Arlovski was KO fodder.. Things change. Also, Fesor ha a major lack of muscle mass, looks like he fixed that a little. As a smaller hw he couldn't afford that extra lost size. He also fought a much bigger guy on roids, and perhaps had some bad luck against a guy who ha a tool to get lucky against anybody on a given night. Fedor will be fine. I believe with some of his mass back he will not be the one punch head hunter he became in his off days.
