RP would get worked by Mikey and have a competitive fight with AB. 140 is a joke. The 2 best fighters (for now, have to see AB vs non-mikey at 140) there now, fights there as secondary weightclasses. RP really the only prospect I've seen that looks nice there, although I could definitely be missing some.
We don't know this
Let Rougarou get a couple more fights under his belt, and then we can say either way. Right now, Mikey SHOULD have an advantage being that he's much more experienced. However, 5 fights from now....things may be different
