The NFL didn't keep individual stats until 1932, its 13th season. It would be another 10 seasons before someone would tip the scales to a weight never seen in an official single-season rushing champion.
Clarence "Pug" Manders, a farm-strong South Dakotan, was playing fullback for the Brooklyn Dodgers when his 1941 team bio read, "Manders is the nearest thing to a pile driver in the NFL today. He weighs 205 pounds … and hits with hurricane velocity."
The official weight for this 6-foot beast was actually 200 pounds.
Fast forward 79 years to U.S. Bank Stadium, where the Vikings on Sunday will face Tennessee's 6-3, 247-pound Derrick Henry, last year's rushing champion with 1,540 yards on 303 carries in 15 games.
In the 88-year history of crowning NFL rushing champions, only former Chiefs running back Christian Okoye, the "Nigerian Nightmare," was heavier than Henry at 6-1, 253 pounds. Henry and Eric Dickerson are the tallest at 6-3.
If you include the AFL years, Buffalo's two-time rushing champ Cookie Gilchrist was especially giant for the early 1960s. He was 6-3, 251 pounds, and mean to boot.
To say Henry is a load doesn't quite do him justice. About five decades ago, the best defensive line in football included a 245-pound Alan Page, a 247-pound Carl Eller and a 248-pound Jim Marshall.
"It's important to make sure you don't try hit him and truck stick him," Vikings linebacker Eric Wilson said.
