I know bouncing around weight classes was more common in Pride and in other orgs, but it seems less common in the UFC. Partially because the weight class differences are so extreme compared to boxing/wrestling etc. Can we come up with a list of people who have had wins in three different UFC weight classes? I know Penn fought at FW, LW, WW in the UFC but he only has wins at LW and WW. Rumble Johnson attempted to fight at WW, MW, and LHW but he wasn't able to make weight at MW. So he has WW, Catchweight and LHW. Anderson has wins at MW and LHW but was never a WW inside the UFC. Who am I missing?
