In 1982, Redskins' offensive line coach Joe Bugel began a practice by screaming "let's go, you hogs" at his offensive linemen. From that point on the nickname "the hogs" stuck, and the Redskins' offensive linemen were known throughout the 1980's as "the hogs".
The Washington Redskins' last Super Bowl win in the 1980's was Superbowl XXII. The average weight of the offensive linemen was 279 pounds. How does that compare to the weight of the offensive lines of both the 2010-2011 Green Bay Packers and Pittsburgh Steelers? A little mathematical analysis on my part (I'm terrible at math, so I can't provide much of a warranty for these results) demonstrates that the average weight of the Packers' offensive linemen is 312.38 pounds, and the average weight of the Steelers' offensive linemen is 321.22 pounds.
Although it doesn't in any way diminish the excellence of the Hogs, they are certainly outweighed by the offensive linemen in this Sunday's Super Bowl. Not only are the offensive linemen in Sunday's Super Bowl bigger than the Hogs, but the Steelers' backup quarterback, Byron Leftwich, weighs only 29 pounds less (Leftwich weighs 250 pounds) than the Hogs!
