Does anyone know why Owen doesn't like James?

Because James "robbed Owen's knight". The specific analysis is as follows:

First of all, Owen was once the hope of the Cavaliers and fans. He not only led the Cavaliers to the championship, but also defeated James. Because he gave the team hope and then let the team down, he abandoned his team in despair. Imagine what a great moment it would be for young Owen to lead the Cavaliers to beat James in the playoffs. But if James comes back in 14, Owen will think that the team will want James, but what Owen didn't expect was that everyone from the boss to the fans welcomed James and said that it would be good to burn the jersey to death. James came back with a mission in a blink of an eye, and everything Owen worked hard became a joke.

Secondly, in the first year of James' return, Owen sat on the sidelines, expecting James to lose and let the team trade him, but although James lost, he won respect. The next year, Owen performed well, but James has almost won all the honors that Owen deserves. Owen seems to have left only the quasi-winner. In the third year, I lost to the Warriors, and I couldn't see the future. In Owen's view, everything he had in the Cavaliers went up in smoke, so Owen chose to leave the team.

Then, after Owen left, James took the Cavaliers to the finals, and then the championship that laid a historical position. The more successful James is, the more honors and praises he gets, and the more ridiculous Owen's previous mission is. If I stay in the Cavaliers, can I still win the championship of 1-2? Drop the mission and become James' successor. Will FMVP be the knight's boss now? The more Owen thinks like this, the more he feels that his original mission is now just a joke.

In the end, James and Owen made up at 19, but the relationship between them was cold again, and Celtic fans booed. Owen almost took the Nets out of the playoffs alone, when James reached the top again. The deeper Owen got into the mire, the more successful James was, and the more Owen hated James.
