Dan D'Antoni, the older brother of new Los Angeles Lakers head coach Mike D'Antoni, will serve as a Lakers assistant coach this season, the team announced Sunday. Dan D'Antoni, 65, spent the past four seasons as an assistant coach with the Knicks when Mike D'Antoni was head coach in New York. He also was an assistant coach for the Suns during Mike D'Antoni's final three seasons with Phoenix. Mike D'Antoni, who recently underwent knee-replacement surgery, didn't coach the team Sunday night in its home game against the Houston Rockets. He hopes to assume his full duties this week.
