Im not sure about this

Because of his comfort level with his teammates and city, and of course, the chance to get an $8 million-$9 million contract, odds are that free agent Jason Kidd will re-sign with the Dallas Mavericks. Yet, he has an intrigue with the New York Knicks that is mutual, and a Knicks source says they plan to try and meet with him once free agency starts on July 1.
Kidd is considering possibilities with Portland and Cleveland, but he always loved New York a lot more than New Jersey. He built good relationships with Knicks coach Mike D’Antoni and Portland’s Nate McMillan when they were assistant coaches for Team USA.

Barring a sign-and-trade deal, the Knicks would be limited to offering Kidd the midlevel exception.
