Because this was the only way to overthrow the tyrannical rule of Su Xi and the Knicks.
Things were tough for the Knicks, who could only bring in reinforcements through the draft.
Following their championship win last season, the Knicks' current roster was about to see some changes.
Gary Payton decided to retire. Having fulfilled his wish of winning a championship, he was off to enjoy life.
Jerome James, who had been brought back as a last-minute reinforcement last year, was also retiring again. He was ecstatic to have another championship ring.
In addition, Trevor Ariza's contract had expired.
The Knicks were hesitant to re-sign him. For one, his agent was demanding an exorbitant salary, and for another, he complained that the Knicks hadn't given him enough playing time.
The Knicks' attitude on the matter was: If you have a better place to go, you're welcome to leave.
Jamal Crawford had one year left on his contract, but it was basically time for them to part ways.
