I think Carmelo is sure to win a ring if he continues playing PF. I think that's what it will take for him just like LeBron.
No PF in the league can defend him. He would be ideal next to a fast PG like Rondo who can take advantage of the small-ball lineup. So far the Knicks have gone with either Raymond Felton, Toney Douglas, or a bunch of old guys in Jason Kidd, Prigioni, Billups, Mike Bibby, Baron Davis, Beno Udrih. It's too bad because they're running out of time with prime Tyson Chandler, who is the ideal big to pair with Melo and cover for his mistakes.
