I don't think that stuff can be taught really. I mean, how often are you going to teach a judoka to stop a wrestler at the corner? In mma maybe, and I suppose that's what you are asking.lol Then we have the age old 'do their sport that you are training'...which would assumed to be that the wrestlers don't do shots.lol
If we are talking judo vs wrestling, it is still always going to come down to the human and their personal concept.
The base point is that with a wrestler you want to square shoulders. Ironic, I know. It'll typically be a shot that the judoka won't be able to handle, but if he does...
there are few judoka, it seems, that can teach the wrestling concept along with judo, and why would they?
Simple, very simple fact here is that judoka hasn't tussled enough wrestlers. Or scrappers; either or. Lets say cross-training.
Seems clearly proven that judoka did not isolate the arm, even when he did have control. That's stress.
Do the human, and do your judo, and fight others that you might fight. Angle on that is huge ammy boxing.
Quick cut is fella went lower than judoka could cope with. Sucked to be him but he could cut that short a hell of a lot quicker than he could learn to deal with a strike. LMFAO.
He's fine, tho. 1 year ammy boxing straight up at 8 hrs/wk. 4 hrs grappling with wide comp, wrestlers, that is. And 1 time/week judo to keep zone reflex.
REeally, just needs to learn to box. Ammy of course. Especially since he's older. It'll be slow, but he's smarter than he prolly thinks. 1 year.
judoka, albeit getting smoked early, didn't do bad imo.
