I’ll take the Elderly Carnivorous Mammal. Old Mongoose Archie Moore could more of less do it all, so he wasn’t in a crouch all the time a la Joe Frazier, but he certainly often shifted into a crouch. So gimme Moore. Such a joy to watch this true encyclopedia of boxing.
Dempsey came to mind first for me - he was so dynamic coming out of that bob and weave crouch to launch powerful, multi punch offensives. The Dempsey “roll” which included the punches leading up to the almighty left hook that dumped Willard exemplified The Maulers form in this regard.
