Talks between the Los Angeles Lakers and Tyronn Lue to install Lue as the team’s head coach abruptly collapsed Wednesday, according to two people familiar with the negotiations.

The sides were unable to agree on contract terms, according to the people, with the Lakers willing to offer Lue only a three-year deal worth nearly $20 million — matching the time remaining on LeBron James’s contract with the team. Lue wanted a longer deal more in line with his status as a championship-winning coach.

Also among the factors leading to the breakdown was the insistence of Lakers management to have final say over the choice of Lue’s assistant coaches, according to the people, who were not authorized to discuss the situation publicly.

The Los Angeles Times first reported Wednesday that the Lakers and Lue had walked away from each other. It was not immediately clear if there were any hope of reviving negotiations.
