The 7 Greatest Spurs in history, ranked by Player Efficiency Rating (PER)

4. George Gervin - 21.8

One of the pioneers of Spurs basketball, George Gervin remains an icon of the franchise to this day. Beginning his professional career, the player known as "the Iceman" spent two seasons in the Continental Basketball Association and American Basketball Association before becoming eligible for the NBA draft.

But after being selected by the Phoenix Suns with the 40th overall pick, he opted to instead remain in the ABA and compete with San Antonio. In 1976, the Spurs joined the NBA as part of the ABA-NBA merger. At the time, San Antonio was part of the Eastern Conference, and the team fell in the first round of the playoffs to the Celtics the following year in their first season in the NBA.

As the Spurs became a perennial playoff team, Gervin started putting together an impressive resume. He would earn six straight All-NBA First Team selections between 1977-78 and 1981-82.

Consistently making defenders look silly and scoring with the patented finger roll that he helped popularize, George finished top two in MVP voting in the late 70s, and was voted to 11 straight All-Star games at the peak of his powers. With the incredible scoring power he possessed, it is no wonder he finished his career with such an impressive PER.
