I bet Arlovski could make LHW, and I think he could compete there too.
Brandon Vera has been fighting as a heavy and wants to drop to LHW, he's already called out Liddell.
Penn could obviously make and dominate at lightweight.
Josh Haynes (the fat kid... with blue hair) fights at 185, and needs to be at 155. I don't ever see him wearing the belt, but i see him giving us some crazy fights.
