This is Bob Baun, the defenseman famous for scoring the Stanley Cup finals game winning goal on a broken leg. He was a rock solid defender in his day, a real champion. Here's a YouTube link to Baun in a skirmish with John Ferguson of all people.
A fellow named Stormin Norman Rumack recently sat down and had a conversation with Baun. He's shared the highlights at his website Late Night Vampire. Baun talks about the Leafs, Punch Imlach, Bert Olmstead and the NHLPA, amongst other topics.
