One of the Suns' best centers was Andrew Lang. He was moved out after four years in Phoenix in the trade that brought Barkley from Philadelphia, but he had started to show real promise in that fourth year: in 24.3 minutes per game, 7.7 points, 6.7 rebounds, and a whopping 2.5 blocks.
He ended up becoming pretty respectable, albeit limited by injuries. His biggest year was '95-'96, which he began with Altanta and finished with Minnesota (in a trade that sent Christian Laettner to the Hawks). He played only 71 games, averaging 33.3 minutes, 11.7 points (!), 6.4 rebounds, and 1.8 blocks.
It must be said that he wasn't much of a passer. In a 12-year career, he totaled 424 assists, which is about how many Stephon Marbury has at the All-Star break of any given season.
Even so, I'd rank him above any of the five on that list, if only narrowly above Mark West.
