For some reason I remember Paul Laus being a very good fighter
About Dave Manson, early in his career he was a good fighter but I think it was after a toe-to-toe fight in January 1988 against Kings Enforcer Joe Paterson where Manson took a huge upper cut in the face at the end that he changed his style and stopped throwing bombs and turned into more of a technical fighter and even sought to end some fights as quickly as possible like Mick Vukota often did. Manson was at his most uncontrollable when someone broke "The Code" and surprised him with a cheapshot such as happened to him when he was punched in the face by Flames veteran tough guy Jim Peplinski in a post-game scrum in a 1988-1989 Conference Final game in Chicago.
I'm not sure how many people had Lindros on here, but did the guy honestly lose a fight in his career? Even once? Probert lost fights just because of the sheer volume of them and the fact that he faced numerous up and comers looking to stick with a team. Not to mention everyone's tough guy. Lindros fought less for sure, but I honestly can't remember him losing a fight. He was big, strong and threw punches with velocity and connected when he did it as well.
Truth is there are a lot of greats you are going to leave off this list. Clark is another guy where I can't recall seeing him ever lose. He never backed down either. He cleaned Neely's clock that one time.
I don't have Chara on here, however while he gets knocked for not being a great technical fighter, the sheer size and strength of him alone makes him a good fighter. The whole "but he's just big" theory doesn't make sense. Andre the Giant was just "big". Would you want a street fight against him?
