May have missed out on points for not getting submission catches. In Japan I think he would have gotten points for all of the control he had from his back even without the catches. They probably look at pulling guard as being taken down and getting controlled. Too bad guy on top didnt need to punch that much, Degroot will have a lot more submission opportunities at pro level where they will have to strike more from the top more or get stood up. So in my head I would say split decision Degroot but judges have their own stuff they look for. I look at decisions like a dice roll.
