He Contradict Himself
there is a funny contradiction in that article. the evidence he cites seems to suggest that you get better by being lighter, i.e.:
the average tonnage of the top two tailbacks on the 32 rosters was 219.9 pounds
The average weight of the 32 starting tailbacks in the NFL last season was 217.8 pounds
There have been five men in NFL history who have rushed for 2,000 yards in a year, and the average weight of the quintet in the season they notched that feat was 214.4 pounds
Over the last 10 seasons, the average weight of the league's rushing champion was 211.8 pounds
...besides all of that, the pot jokes were REALLY lame!
