Head coach Tyronn Lue and the Cleveland Cavaliers have begun conversations on negotiating a contract extension, league sources informed cleveland.com. Both sides are confident that a pact can be reached relatively soon. Lue, 39, never signed a new deal when he took over for the fired David Blatt in January, He was working under a four-year, $6.5 million deal as Blatt's top assistant, and essentially bet on himself by not signing the three year, $9.5 million deal etched out for him to be the head coach by the team and his representatives. Assistant coach Larry Drew had a team option for the 2016-17 that was picked up recently, league sources revealed to cleveland.com. Lue's maneuver, first reported in April by ESPN.com, paid off -- Lue guided the Cavs to their first championship. LeBron James endorsed him as the "greatest coach in the world." Recently, the Toronto Raptors, whom Lue and the Cavs bounced from the Eastern finals, gave coach Dwane Casey a new three-year, $18 million deal. - See more at: http://www.cleveland.com/cavs/index.ssf/2016/07/tyronn_lue_cavs_coaches.html
