What is the real reason why the Rockets traded Tracy McGrady?

The real reason why the Rockets traded McGrady is:

Previously, McGrady was the Rockets' highest-paid player and one of the highest-paid players in the league. He believed that he should enjoy privileges. So when he feels he needs more playing time, he will bring it up publicly.

However, the Rockets are not really ready to put Tracy McGrady into the lineup. Only after the Rockets return to Houston after the Eastern Conference road trip, the executives will meet to discuss the Rockets' rotation lineup, and Determine if McGrady should be part of the regular rotation. Coach Rick Adelman once wanted McGrady to play 7 minutes per game, but McGrady publicly asked for more playing time. In order to avoid intensifying conflicts among the team, the Rockets decided to trade McGrady.
