My father actually did play in the 1937 Grey Cup Game, his first of seven Grey Cup appearances, but I'll resist the temptation to claim he was the MVP of the game. In fact no MVP awards were made back in the 30s. Record keeping was minimal, and was generally restricted to scoring. The first Grey Gup MVP award went to Charlie Sheppard of the Winnipeg Blue Bombers in 1959.
The 1937 AL MVP was Charlie Gehringer of the Detroit Tigers.
The MVP of the Stanley cup in 1940 was Ebbie Goodfellow.
Ottawa QB J.C. Watts won the MVP despite losing the game.
The MVP of the 1941 Stanley Cup was a man named Bill Cowley.
