Balfour was a defensive forward, a penalty-killing specialist who won a Stanley Cup with the Chicago Black Hawks in 1960-61. He was drafted away from the champion Hawks by Boston immediately after his Cup victory but stormed out of the Bruin training camp after a run-in with head coach Phil Watson.
Detroit general manager Sid Abel, a well-known linemate of Gordie Howe's from the Production Line days, tried Balfour on the left wing of Mr. Hockey's line but the aging Spider didn't quite make the cut. Balfour, who began his career with the Toronto Maple Leafs, was reinstated as an amateur in 1964 and joined the Galt Hornets in the OHA Sr. league, where he became a playing-coach a year later. Balfour resigned from Galt in 1967 and rejoined the Toronto Marlboros, the team he had first played for as a teen.
