David Robinson (1989-1990)
The Spurs had to wait two years for Robinson to finish up his Naval commitment, but the big man was well worth the wait. “The Admiral” averaged 24.3 points, 12 rebounds and 3.9 blocks his rookie season, unanimously winning the league’s Rookie of the Year award. He also helped the Spurs go from a 21-61 record the year before to a 56-26 mark his rookie year. For those of you who don’t feel like doing the math — that’s an improvement of 35 wins!
