4. Arvydas Sabonis
Arvydas Sabonis was one of the most skilled big men in the world during the late 1980s and early 90s. He averaged 20.4 points, 12.3 rebounds and 2.0 blocks and shot 38.7 percent from three during six seasons in Spain. He led Lithuania to a bronze medal in the 1992 Olympics, posting averages of 23.9 points, 12.5 rebounds, 2.6 steals and 2.1 blocks on 54.6 percent shooting.
He didn't start his NBA career until he was 31, but Sabonis was still a force at times with the Trail Blazers. His best season came in 1996-97 when he averaged a double-double (16.0 points, 10.0 rebounds) while dishing out 3.0 assists and shooting almost 50 percent from the field.
Sabonis would have been one of the best big men in the NBA for a decade had he entered the league earlier. Still, his time - and PER of 21.2 - in Portland is memorable.
