Cowens just wanted the ball more than the bigs he was up against. The ball is right there waiting for a rebound and Cowens would just punish the guys who tried to go get it first. Every loose ball was like a playoff game...no one wanted to play against him.
Cowens vs Bob Lanier or Kareem was a sight to see.
NBA finals (1974) Cowens played all 18 playoff games
PPG 20.4
RPG 13.3

Watch clips of that series the Celtics took the Bucks in 7....Tommy Heisohn head coach killing the refs, Cowens at total war with Kareem. Havlicek And Oscar Roberston two more hall of famers.
The city of Boston was ON FIRE for that series. Celtics took game one, but Kareem hit for 35 points and the Bucks got game two. Kareem's length had hammered Cowens inside on defense so Cowens switched and started taking more outside shots and? He hit'em!
What a show.
The rest is history.
