Dave Schultz 1974-75
Played 76 games, had 26 points and 472 penalty minutes, played 17 more games in the playoffs adding 5 points and another 83 penalty minutes and won the Stanley Cup.
He had 25 fights in the regular season and 8 more in the playoffs for a total of 33 fights. He fought O'Reilly, Gillies, Irvine, Snepsts, Magnuson, and Unger among many others and thus fought many of the top heavyweights of the year.
He almost singlehandedly changed the way the game was played, requiring teams to stock their rosters with tough players and/or goons to deal with The Hammer. He went about his job like no one else before him. Sure, there were guys who were tough and fought but no one did it like him, the art of intimidation was taken to a whole new level and forced the NHL to change the rules of the game.
No one until maybe
Rob Ray and
Bob Probert forced the NHL to change how the game was played(the tie down rules).
