The Cleveland Cavaliers firefighter coach, Tyronn Lue, after 0-6 starts, according to sources

Tyronn Lue did not survive the first month of the season without LeBron James.

The Cleveland Cavaliers fired their coach Sunday, told the Associated Press two people aware of the events. The Cavaliers are on a 0-6 start without James, who left Cleveland this summer for the second time in his career and signed with the Los Angeles Lakers as a free agent.

The Cavs did not make enough progress under Lue and the team decided it was time to change before the situation worsened, said the population, who had spoken to the PA under the guise of anonymity because the team did not comment on the move.

Lue guided the Cavaliers to an NBA title in 2016 – Cleveland's first professional sports championship since 1964 – and helped the team to four consecutive finals.

The players seemed to be caught off guard by Lue's dismissal. Star player Kevin Love, who missed the last two games with a sore left foot, posted a message to Lue on Instagram.

"You helped me see the big picture," Love wrote. "Experiences and teaching points that change lives. Just love and admiration. Know that we are going to work on something bigger together again. THANK YOU."

Love also posted a photo of him and Lue on the field at Oracle Arena after the Cavaliers pulled themselves up against a 3-1 deficit and won the seventh game of the 2016 Golden State Final.

James also expressed gratitude to his former coach on Twitter.

"Lue thanks you for the memories and, more importantly, our partnership bringing a championship to this deserved base of cities / fans," said James. "You know how to find me."

Lue, 41, is three years old to sign a $ 35 million deal that he signed after the Cleveland victory. He played 128-83 in three seasons or more as a coach.

We do not know immediately who will replace Lue. Assistant Larry Drew seems to be a likely candidate. He replaced when Lue retired for 10 games last season while he was suffering from chest pain, insomnia and anxiety.

The Cavaliers hoped to stay competitive without James, but they were outclbaded. They dropped their sixth straight game on Saturday night against Indiana and begin their worst start since losing their first seven games of the 1995-96 season.

Cleveland has lost at least 16 points in six losses and the club has not led in the second half. The Cavs were also affected by defense and communication problems, and sometimes seemed disorganized.

The Cavaliers welcome Atlanta Tuesday night. Led by rookie Trae Young's 35 points, the Hawks added 22 points to the Cavs in the Cleveland home opener last week.
