Harris is not the greatest ever. He is not even the greatest Bomber ever. He is arguably not even the greatest Canadian or Canadian Bomber ever
Greatest ever - Doug Flutie by a lot (Jackie Parker often cited as 2nd best, although Anthony Calvillo and Mike Pringle could also get consideration)
Greatest Bomber - Milt Stegall
Greatest Canadian Bomber - Based on tenure and making an apples to oranges positional comparison, I’d put Chris Walby, Joe Poplawski, and Bob Cameron ahead of Harris.
Greatest Canadian - Harris’ overall career including his BC time gives him a puncher’s chance to lay a claim (especially with the all-time Canadian rushing record). But he has only won the MOC award once and was never MOP. Jon Cornish (3x MOC, MOP), Tony Gabriel (4x MOC, MOP), and Russ Jackson (4x MOC, 3x MOP) all did better. Cornish and Jackson also won the Lou Marsh Trophy, and Jackson was given the Order of Canada, was Grey Cup MVP, and was indicted into the Canadian Sports Hall. Of Fame). For me Jackson is the best. Again, if a positional comparison is factored in, Walby could lay a claim.
