McG is a kickboxing GSP. The comparison would be their most effective tool that everyone overlooks with Conor: That athleticism. Conor is the most athletic current fighter; He's explosive, quick, great reflexes, and he doesn't get tired. GSP's wrestling wasn't his most effective tool, his superior wrestling was a SYMPTOM of his athleticism, if he had the skills but not the cardio and explosive muscle fibers, he would be a run of the mill, top ten WW McWrestler. If Conor wasn't as athletic as he is, he would just be a good McKickboxer, a Dustin Porier or a Matt Brown.
