"Don't get it..." Meh.
Given a choice, you don't think ownership's going to be REALLY temped to just let Ray Allen walk, if it means that they get out from under the luxury tax (and start becoming a recipient of those dollars?)
Sure, it's nice to have an expiring contract... but as it stands today, we're lacking in anything to pair it with. There really aren't THAT many cases where good players get dumped for nothing; Kirk Hinrich recently, but the Wiz didn't send back an expiring contract, they were able to just absorb his deal.
Unless our young guys prove to be pretty good ballers, just having an expiring contract in February isn't likely to do us any more good than having Ray's expiring contract did us last February.
Besides... if ownership doesn't believe we're truly a title contender, they aren't going to pay the lux tax if they've got any way out of it. Can't blame them. If we're losing Ray Allen, I can't see that we're legit contenders.
If there's value coming back to the C's in addition to Curry's contract, that's when you consider a deal - but the Knicks are pretty depleted at this point. They'd have to give us Gallinari, at a minimum, for ownership to sign off on continuing to pay the tax.
