I considered him, but I wanted to mix up the eras.Big Mark Eaton
Named an NBA All-Star in 1989, he was twice voted the NBA Defensive Player of the Year (1985, 1989) and was a five-time member of the NBA All-Defensive Team. Though limited offensively, the 7-foot-4-inch (2.24 m) Eaton became one of the best defensive centers in NBA history. He led the league in blocks four times and holds the NBA records for single-season blocks (456) and career blocked shots per game average (3.50). His No. 53 was retired by the Jazz.
