18. Milwaukee Bucks: Kareem Abdul-Jabbar, 114.7 Win Shares
It only took six seasons in a Bucks uniform for Kareem Abdul-Jabbar to achieve the highest Win Shares total in Bucks franchise history. Kareem averaged a preposterous 30.4 points per game in those six years for Milwaukee. He also won the MVP award twice in addition to being the 1971 Finals MVP. He is the NBA’s all-time Win Shares career leader at 273.4, and he posted the highest Win Shares season ever in 1971-72 at 25.4.
It must be noted that Giannis Antetokounmpo is already third for the Bucks at 87.5, averaging 12 Win Shares over the last six seasons. If he keeps that pace, Giannis should pass Kareem just three seasons from now as Milwaukee’s new No. 1.
