Get the feeling this deal would have been done already if Noah and his contract weren't around. The two of them would be taking up a big part of the cap (Noah and Anderson) if they were both were on the roster.
Best case scenario if Melo isnt moved this summer, he comes back in great shape. Some good teams find that they need more firepower and come up with a better offer. If Melo is playing well, staying healthy, Perry should be in a better position to bargain.
The same goes for Noah, harder to move, but if he comes back relatively healthy amd playing well, a contender might be interested. Ways to go before we get to that point though.
Its not the end of the world (really) if Melo is here to start the season. Not another Ewing trade please. Thats the real test of whether or not the Knicks front office finally gets it.
