Of course the Knicks would want to do that trade. Ainge isn't stupid though, so I don't even see the point of somebody printing that quote. To me Shumpert is a Courtney Lee/Avery Bradley type. Not someone you need to go out of your way to acquire.
Amare is untradeable, Felton is a far below average starter in today's nba, chandler would be a nice piece for a team who is one player away from contending, and Carmelo is a ball hog. I have no interest in anyone on that team, and I hope Ainge feels the same way.
