Rumors have surfaced that with just a few days to go before the start of training camp, the NBA's Golden State Warriors are on the verge of replacing legendary coach Don Nelson with assistant Keith Smart. It is believed the change will be officially announced before the team's media day Monday, in time for the team's first practice on Tuesday. Nelson became the league's all-time winningest coach last season, surpassing Hall of Fame coach Lenny Wilkens.
