“CFL 1980 CALGARY STAMPEDERS AT WINNIPEG BLUEBOMBERS”
From CFL Video
The Blue Bombers playing on grass with Dieter Brock as their QB. Dieter Brock was a very successful American QB in the CFL, with a big arm, who was very accurate. But somehow never caught on with an NFL club until the Los Angeles Rams signed him in 1985 when he was already in the 30s. But he could throw the football and you put him on a NFL club with a good passing game and offensive line, Dieter would’ve probably been successful in the NFL.
