Well, Lionel Conacher won the Canadian light heavyweight Championship, and fought Jack Dempsey, one of the greatest fighters of all time. An absolute freak of an athlete.
Eddie Shore was tough. Also a great player
John Ferguson was a really good fighter.
I always think of tough as a different thing than a goon. Goons barely play, resting themselves for the time till they fight. Tough guys, like Cam Neely, and Gordie Howe, take a regular shift, do it very well, and can take, and dish out, the physical stuff. Those are the guys you win with. The others are circus geeks, cheered on by the masses the bite the heads off their figurative chickens.
