Al Renfrew, coach of Michigan's 1964 national championship hockey team, died Monday. He was 89.

Renfrew amassed a 222-207-11 (.517) record in 16 seasons as coach of the Wolverines from 1957-1973.

The Toronto native played at UM from 1946-49, scoring 91 goals and adding 81 assists for 172 points, and was a member of the Wolverines first national championship team in 1948.

He and wife Marjorie are also credited with creating what became the iconic M-Go Blue banner that football players touch while coming of the tunnel at Michigan Stadium.

In 1962, with the football team mired in a slump, Renfrew decided to help his coaching colleague and former classmate "Bump" Elliott. So, Marjorie stitched a yellow block M on a 6-foot wide blue sheet, according to UM historian John U. Bacon.

Elliott let players touch the homemade banner in the tunnel on the way out to the field and UM beat Illinois 14-10, snapping a four-game losing streak. The banner was moved out to the field the following season and subsequently has grown to 4-feet high and 40-feet wide in size.
