Joe Riggs? I know he fought both Cabbage and Nick Diaz. He was supposed to get a title shot against Hughes but didn't make weight, so I think he's been as low as welterweight.
Did he also fight at middle and light heavy? Even if not, that's quite a range.

Silva: The only one that I noticed that I miss a lot is of course the kicks on the ground because I use that a lot. That is the one I miss the most.
