Well... more than the Knicks.
The Knicks are committed in a direction around Amare, and to get Melo would have to strip themselves of a few pieces that are part of the reason they are doing pretty well thus far this season. Melo ending up at NYK would result in the franchise taking a backward step (I think).
The Nets will build completely around Melo, and don't have to sell the farm to do so. Add to that, they have an owner who'll be prepared to spend (tho' to be fair, historically that's not something Dolan's had a problem doing either).
