Cornish, a native of New Westminster, British Columbia, led the Canadian Football League, with 1813 rushing yards. He also set his own CFL record for the most rushing yards in a regular season by a Canadian.
Cornish becomes the third player in CFL history to win the Lou Marsh Award, following former Toronto Argonauts quarterback Joe Krol of Hamilton, Ontario in 1946 and former Ottawa Rough Riders quarterback Russ Jackson of Hamilton, Ontario in 1969.
Cornish won the award despite the fact the Stampeders failed to participate in the Grey Cup. Calgary lost 35-13 to the Saskatchewan Roughriders in the Western Final at McMahon Stadium on November 17.
Cornish was however the first Canadian to win the CFL's Most Outstanding Player award since Tony Gabriel of the Ottawa Rough Riders won the award in 1976.
