MIAMI — The story of a long-time NBA veteran point guard out of Oakland seeking an NBA championship with the Miami Heat while on the back end of his career in his 30s is not unique to Damian Lillard. It is a story, in fact, previously written. By Gary Payton, In 2006. Payton, now a coach with the halfcourt Big3 circuit, was back in Miami on Sunday as part of the league’s tour, working the officials at Kaseya Center with the same vigor seen before and during that 2005-06 championship season with the Heat. And, yes, as is the case with Lillard, Payton is all in on Lillard’s desire to relocate to South Florida. “It is the same thing as it is with me,” Payton said after coaching his team Sunday.
