Maia's BJJ is going to be in full-bloom with this matchup IMO. If Story looks to engage in the clinch and press Maia against the cage, he's going to be at great risk for legtrips and takedowns, where he'll fall into Demian's world. Both of their standup should nullify each other to a good degree, so I think Maia's exemplary groundgame is going to be the deciding factor.
