From RealGM:
"Marc Berman of the New York Post reports that the Knicks may make a play for Toronto’s Keon Clark in the offseason. If the Knicks pick a shooting guard in the draft, look for their GM Scott Layden to try to sign a free agent big man. Clark is on the top of his wish list.

The shot-blocking 6-11 sixth man is hardly a lock to re-sign with the cost conscious Raptors and can be had for the mid-level cap exception ($4.75M). The Sixers are also believed to be interested in Clark. The Knicks may not be very interested in Clark if Maryland power forward Chris Wilcox falls to the Knicks with the seventh pick in the draft.

The Knicks’ cap situation makes it impossible for them to bid on a big-money free agent. The Raptors, within $3 million of the luxury-tax threshold, won't break the bank for Clark, wondering if he's reached his potential. He's got a suspect work ethic and reportedly doesn't get along with Vince Carter. The Raptors already overpaid last summer to keep Jerome Williams, who didn't have a good year, and may be gun-shy.

Several NBA teams will be looking to split their $4.7 million exception on more than one player, but Clark could be worth the entire amount. Other free-agent big men the Knicks are expected to have on their shopping list include Utah's rookie starting center Jarron Collins, twin brother of the Nets' Jason, Wizards power forward Popeye Jones, Celtic sixth man Rodney Rogers and Minnesota center Radoslav Nesterovic."

From Insider:
"Jun. 21 - Scott Layden is still trying to shake things up and Spree is his most valuable commodity. If Wilcox is off the board when the Knicks draft, they may have no choice but to draft either Dajuan Wagner, or a small forward and move Spree. The New York Daily News is reporting today that the Knicks turned down a Glenn Robinson-for-Spree offer"
