Paul Silas, a member of three NBA championship teams and LeBron James’ first coach in the league, has died at the age of 79.

The Houston Rockets and Stephen Silas have an agreement for the Dallas assistant to replace Mike D'Antoni as coach, multiple people with knowledge of the deal said Wednesday. Silas inherits a team led by a pair of former MVPs in Harden and Russell Westbrook. The longtime NBA assistant has worked worked with elite guards before, most recently in two seasons with the Mavericks and 21-year-old sensation Luka Doncic. The nine seasons as a Charlotte assistant for Silas included time with Kemba Walker, and he was with Golden State when the Warriors drafted Stephen Curry in 2009. Paul Silas spent 16 years as a player in the NBA and another 22 as a coach.
