Yeah, it's Red. He was the architect behind all of these Championships.
I know, it's Wiki, but: "In the 1956 NBA draft, Boston Celtics coach Red Auerbach set his sights on Russell, thinking his defensive toughness and rebounding prowess were the missing pieces the Celtics needed. In retrospect, Auerbach's thoughts were unorthodox. In that period, centers and forwards were defined by their offensive output, and their ability to play defense was secondary." BTW, in this same draft he took Heinsohn and KC Jones.
Then he drafts players like Cowens, JoJo White, Havlicek, Bird, McHale, trades for players like Parish and DJ. He was playing chess and everyone else was playing Candyland.
Thirteen players who played for Auerbach have been inducted into the Basketball Hall of Fame, that's not counting the ones he acquired as GM!
Yeah, it's Red! Light the cigar big guy!
