I think it's pretty obvious.
Fab Melo and Isaiah Thomas.
In the second round, John Leuer, Rick Jackson, and Keith Benson. The Knicks might as well buy two extra picks. And seriously, forget about Jared Jeffries.
And maybe consider signing Robert Swift. He's getting 20-20 games with the Tokyo Apache. He looks like this now: http://www.tokyoapache.com/en/team-2010/roster/robert-swift/ and apparently he's part Japanese.
