Sources close to Knicks president Donnie Walsh say he has targeted Kings 6-foot-11 shotblocker Samuel Dalembert as the likeliest free-agent catch this summer.

Walsh's old-school principles have made adding a big, bruising starting defensive center to play alongside power forward Amar'e Stoudemire as his No. 1 priority. It might be a strong enough urge to sacrifice what could be maximum cap room in 2012, essentially sacrificing a shot at point guard Chris Paul.

The Knicks realize some top free agents likely will stay put or be out of their financial range. Memphis' Marc Gasol and Dallas' Tyson Chandler are expected to re-sign, and the Clippers probably will match an offer to the young DeAndre Jordan.
