Just to remember Rick Story had never been subbed before fighting Maia. Maia was frustrated when he got KOed by Marquardt and trained mainly strikes for a good while, outstriking Dan Miller to a UD and handling well strong guys in Munoz, who won a SD, and Weidman, being Maia a stretched WW. Maia can exchange standing alright, but now he is back to his Jiu Jitsu, he is proud of this and he know tricks no one knows. The way he ragdolled Story was incredible, always advancing to the final neck crank, also a versatile final move.
As Joe Rogan says, a black belt who finishes black belts.
Fitch will have to keep standing, IMO, and even there, I don't see advantage to him (or Maia TBH).
