A favourite of mine was Bomber fullback Bob "Hoss" Houmard. If anyone remembers his style of play, a big 235 lb straight ahead fullback then the nickname sure fit. I remember Jack Matheson used to love the guy. Another personal favourite of mine was fullback Jerome Bettis who was called The Bus.
Another of the nicknames I miss are the defensive line Front Fours. Many years ago, the Ottawa Rough Riders had Capital Punishment. The Stampeders had The Four Trees. The Eskimos had Alberta Crude. In the NFL, the LA Rams had The Fearsome Foursome & The Vikings had The Purple People Eaters. Pittsburgh Steelers had The Steel Curtain that originally was only the name of their front four but later encompassed their entire defense. The Miami Dolphins had The Killer Bees to describe their DL & Chicago had The Monsters Of The Midway.
In the CFL, the Bombers coined the nickname of The Hogs for their offensive line a decade before the Redskins called theirs by the same name. Bill Frank was the Head Hog. Too bad nicknaming offensive & defensive lines have gone out of style. It really added to the games. The media & fans would love it when they'd talk about Capital Punishment vs The Hogs.
