Another thing is that the Knicks are damned if they do, damned if they don't. If you resign Melo, you're REALISTICALLY a ECF appearance team at best, even if you sign Rondo in 2015. Miami and BK got this year and maybe next, AND you have to deal with Indiana the years after.
On the other hand, if you don't sign Melo, you have to go out and tank. Like @
Trip said, you better be stockpiling on picks, because the odds of you drafting a Russell Westbrook or James Harden are slim. Now if the Knicks tank, you guys will be pissed by year two of this plan, when you end up with nothing but 3rd option players on your team. Sure you can always package picks to get stars, but there aren't that many players you can likely get during trade. Outside of getting possibly DeMarcaus Cousins or maybe Anthony Davis in a 3+ years, what star players can you see the Knicks acquiring in trades?
