Is it right THIS triangle theory?

Hi everybody. "Boxer gives problem to slugger, slugger gives problem to brawler, and brawler gives problem to boxer". I dont know where I hear this, I think is something that Cus D'amato said. But for what i saw, it has a lot of sense. Only with look to Ali (boxer), who had hell of fights against Frazier (brawler), but smokin Joe lost convincingly against Foreman (slugger). I heard too that for this reason, Mike Tyson never fought old Foreman. Im thinkin all this this week cause looking forward in Lara-Canelo, I know that the first is pure boxer... but what is Canelo? he slugged a brawler like Angulo, but he boxed against Austin Trout. Maybe here is the key. EDIT: I have to make aclaration, I always heard like I said, but like other people here down said, maybe I confused definitions (english is not my main language). With brawler I want to say people like Tyson, Frazier (I guess the real term is swarmer). And with slugger I mean people like Foreman, Mayorga, etc. Greetings guys :boxing:
