With or without Anthony, the Knicks are expected to be over the salary cap this summer because of the contracts of Amar'e Stoudemire ($23.4 million), Tyson Chandler ($14.6 million) and Andrea Bargnani ($11.5 million), which run through 2014-15.
So Jackson probably will have to trade one of those three players if he wants to reshape the roster.
Mike D'Antoni and Gregg Popovich, speaking before the Lakers and Spurs played Friday night in San Antonio, both lauded Jackson's hiring.
"Obviously, he's a knowledgeable basketball guy and they need that right now," said D'Antoni, who coached New York from 2008 to '12.
Popovich said it would be "weird to see him up in the boxes, instead of on the sideline."
"He has a hell of a mind," Popovich added. "And being a coach is sort of a pain in the ass. He's a smart guy."Information from ESPNNewYork.com's Ian Begley and ESPNLosAngeles.com contributor Matthew Tynan was used in this report.
