Cavs coach Lue in new 5-year deal

Coach Tyronn Lue has secured a new five-year deal worth $US35 million ($A47 million) with NBA champions Cleveland Cavaliers, the Cleveland Plain Dealer reports.

Lue, 39, took over after David Blatt was fired in January and led the Cavs to the title in his first head coaching role.

The rookie coach was praised for having a good relationship with LeBron James, who had clashed with Blatt prior to his termination.

Lue had not signed a contract as a head coach and was working on a four-year deal worth $US6.5 million ($A8.7 million) as Blatt's top assistant. Negotiations began following their championship triumph.

After compiling a 27-14 record down the stretch in the regular season the Cavs caught fire in the playoffs, sweeping Detroit and Atlanta, before beating Toronto in six games and rallying from a 3-1 deficit to stun Golden State in the Finals.
