About 15 years ago, Sports Illustrated's annual NBA issue had a cover story called, "The Enforcers." Basically it was a piece about all the bad-ass guys in the NBA who were their team's protector.
This was when Maurice Lucas of the Trail Blazers was in his heyday. They had a picture of Maurice standing in a dark alley and, you knew, no one was gonna mess with Maurice.
The article appeared, if I recall correctly, the season after Kermit Washington threw THE PUNCH that broke Rudy Tomjanovich's jaw. So they played up how much of an enforcer Kermit was. My own recollection of Kermit is that he was a journeyman player, who was really a kind soul at heart. The Rudy T incident was not at all indicative of his character and in many ways, his career was over after that incident.
Anyway, in this article, they asked Bob Lanier (6'10, 265, size 16 sneakers, career 20.1 ppg. 10.1 rpg) who HE thought was the biggest enforcer in the league.
His response? Wilt. I clearly remember Bob saying, "When Wilt picked me up (now think about that) over here, and put me down over there, I knew he was the biggest badass."
