I would consider him retired. The guy is one greedy bastard.
On October 31, 2004, the Minnesota Timberwolves offered Sprewell a 3 year, $21 million contract extension, substantially less than what his then-current contract paid him. Insulted, he publicly vented his outrage, declaring, "I have a family to feed." He declined the extension, and, having once more drawn the ire of fans and sports media, had the worst season of his career in the final year of his contract.
He hasn't played since then
