Scotty Bowman as Coach/GM in Buffalo.
Had to give permission for any of the guys on the team to be interviewed.
Once pulled his goalie with over 6 minutes left in a game because he wanted to embarrass them. Similarly, he pulled Tom Barrasso from a game against the Wings and after giving up an ENG, told Barrasso to stay on the bench rather than go in - which Barrasso rightly took personally - and gave up two more ENGs rather than let Barrasso finish the game.
The lawsuit from Rick Martin over forcing Rick to play with a bad knee that ended his career. It's that he was complicit in it - Martin settled out of court for $2 million.
Trading any player who he had beef with, often as far away as possible. Trading Larry Playfair to LA was a direct result of Larry telling Bowman he didn't want to fight any more after Playfair broke open one of the Sutter twin's faces in a game. McKegney traded to Quebec was another, Martin to LA. Dealing two captains (Gare and Schoenfeld) to the Wings where Schoeny said "I have nothing good to say about that man" on the way out of town. Gare had similar comments.
His feud with Real Cloutier that put Cloutier into the IHL and retirement - the talk at the time was he was still mad Cloutier had refused to play for him in Montreal and went to the WHA instead.
Having a direct line installed to the bench so in game he could call down to the HC and meddle in what was going on during home games when he was officially just the GM.
He had a moment where he called ever player on the team into a meeting one at a time to ask them if they had called a reporter to let the reporter know that Dave Andreychuk's supposed fall down some stairs that resulted in him missing the playoffs with a broken collar bone was due to Andy actually f***ing around on an ATV. He made every player come in to his office with the reporter there.
Made him so miserable that Perreault said he retired rather than play for him.
Yeah, great coach and an excellent eye for talent in personnel roles, but with control his ego was rampant and he lashed out like a child at anyone who he felt wronged him.
