Maia can take Story down if he wants to, I don't think he needs to pull guard.
Either way, sub for Demian!
Even thought Maia is dropping down I think Story is probably the bigger man(I think he cuts more weight). He is one of the bigger and stronger WWs out there. I think Story could muscle him around a little at first but I think eventually he gets winded and Maia finds the sub.
Maybe my memory is off but I thought Demian took Stungun down quite easily, but Stungun just injured himself on the landing?
Stungun is a huge 170 and has excellent TDD.
