Ronnie is a southern Black guy, who probably grew up throwing the hands with other Black dudes all his formative years. Nasser at most, strong armed a few soft Germans. Ronnie was also a cop for a number of years. Sure, some of it was in public relations, but the early years would've been on patrol, and he'd have learned joint locks, throws, etc.... and how to be aggressive / offensive quickly when it matters.
My money's on Ronnie all day in his prime.
