In the 1971–72 NBA season, the Lakers hired former Celtics star guard Bill Sharman as head coach. Sharman introduced morning shoot-arounds, in which the perennial latecomer Chamberlain regularly participated (in contrast to earlier years with Dolph Schayes) and transformed him into a defensive-minded, low-scoring post defender in the mold of his old rival Bill Russell. Furthermore, he told Chamberlain to use his rebounding and passing skills to quickly initiate fastbreaks to his teammates. While no longer being the main scorer, Chamberlain was named the new captain of the Lakers: after rupturing his Achilles tendon, perennial captain Elgin Baylor retired, leaving a void the center now filled. Initially, Sharman wanted Chamberlain and West to share this duty, but West declined, stating he was injury-prone and wanted to solely concentrate on the game. Chamberlain accepted his new roles and posted an all-time low 14.8 points, but also won the rebound crown with 19.2 rpg and led the league with a .649 field goal percentage. Powered by his defensive presence, the Lakers embarked on an unprecedented 33-game win streak en route to a then-record 69 wins in the regular season. Yet the streak led to one strangely dissonant event. According to Flynn Robinson, after the record-setting streak, Lakers owner Cooke sought to reward each of his players—who were expecting perhaps a "trip to Hawaii"—with a $5 pen set. In response, Chamberlain "had everybody put all the pens in the middle of the floor and stepped on them."
