I grappled with so many Judo black Belts that "had been doing it since diapers" and ironically enough, I came from a Sambo gym. One of my main teammates was a Judo black belt and we'd cross train with really good kodokan with their black belt team, just doing open mats mostly...hard rounds, always started standing, really there to get our upper body wrestling better and have consistent strong rounds vs people who had good bases, takedown defense and offense etc. Sometimes we'd even just wrestling rounds instead of rolling...a great resource, surprising how many gyms don't do stuff like this or dont feel its a priority.
That said? I would dump most of the black Belts on their heads. It was shocking how much easier they were to take down than other Sambo guys or wrestlers. How much more reliant on the gi they are and how prone to giving up their backs and weak to body locks etc. Morales is a freak athlete but he should not rely on his "Judo" or "wrestling" backgrounds from Ecuador, he should be bringing in guys like Yaroslav Amosov to train with him or taking trips to train with guys like that, go to Sean Bradys gym, work with Brady and they have some guys from Georgia and Tajikistan who are good and 170lbers like Samandar Murodov...just get in as many rounds as possible vs guys like that...hes gotta be full "i wanna smash Islam" mode. Hes young, he has very little experience compared to Islam, hes gotta take that seriously.
