Terry McGovern, the original prototype of Mike Tyson.

McGovern was a brawler, as was Dempsey, Marciano, and even Tyson. Yes they used some defense to get in, like bobing and weaving, or being arkward. But mostly they were brawlers, slugging it out once they got in.

 

I would not call any of those guys brawlers.

Dempsey and McGovern were not brawlers they were scientific offensive specialists.

There is nobody alive today who could teach you what they knew.
