Steve Nash still doesn't fully understand why Mavericks owner Mark Cuban allowed him to leave via free agency in the summer of 2004.

"It was strange to me after all the contracts he had overpaid that the buck would stop with me," Nash said in a lengthy interview with ESPN's Bill Simmons.

Nash far from regressed after his stay in Dallas. He won a pair of MVP awards with Phoenix and averaged close to a double-double last season.
