From what I can gather, Rick Sund is exploring sign-and-trade scenarios for Jamal Crawford. But, so far, Sund does not have the green light to approve a transaction that results in a luxury tax payment. As long as that’s the case, I don’t see how it can happen.
Update 12:08 a.m.: The Knicks have expressed interest in Crawford, as reported by Alex Kennedy Hoopsworld.com and Sam Amick at SI.com. But still no word that Sund has been authorized to spend into the tax. Howard Beck of the New York Times reports that the Knicks will be over the cap once they complete their recent transactions. Their trades thus will be subject to salary-matching rules.
Update 10:09 a.m.: There’s still no indication that Sund has been authorized to spend more than the tax threshold but late last night he was looking for ways to gain some salary relief to get the Hawks further under the tax line. I’m not sure how the Hawks can shed significant team salary (money that counts towards the cap and tax)
