The relationship between Kemba Walker and Brad Stevens was reportedly filled with tension, sources told Jared Weiss of The Athletic.

Stevens was perceived to be harder on Walker than other star players, including criticizing him for defensive mistakes.

Despite their disagreements, Stevens and Walker had a productive relationship with mutual respect for each other.

Walker's health issues, the team's performance, and boos from TD Garden fans made him willing to accept a trade this offseason.

Multiple players reportedly welcomed a coaching change from Stevens, who many felt favored Marcus Smart over others.

After inquiring about a potential midseason move, a Celtics player told Blake Griffin not to come to the team due to the dysfunction.

Walker was traded on Friday to the Thunder.
