Rose for Calderon/Lopez works.
The Knicks would have 27$M in space to go after a Center like Dwight Howard, Pau Gasol, Al Horford or even Hassan Whiteside, assuming Afflalo opts out which he likely will.
I think Dwight would seriously consider the Knicks. He is good friends with Melo and has in the past yearned to be coached by Phil. He has a great deal of appreciation for the Triangle and an offence that caters to big man play. If we can find a taker for O'Quinn, the Knicks could even keep Afflalo.

That's a much much better starting 5 than last year and likely good enough to compete with any team in the East. On the flip though it also screams of a NY Knick team of the past where there's a lot of stars in one lineup past their athletic prime. The only reason I could see it work is KP. He's so young and athletic and full of promise that he can engage the team into being something different from the Knick teams of the past which were filled with stars past their prime on a 1st round playoff exit team. If KP improves over the summer and can be relied on to give that starting 5 energy, defense and great outside shooting - perhaps it can work. But one thing that lineup does not lack is talent. I don't know if talent would fit.
I also believe that Phil wants to build a team with character guys who play for the name on the front and nothing else. Guys like Robin Lopez do that. Even Calderon is an outstanding teammate. The Knicks may lack talent right now to be a contender but with their anticipated 27$M in cap space, after using that to sigh some guards, we may be a team talented enough to make the top 6 of the East.
I'm torn - but considering we aren't giving up any draft picks to put that team together or young players im surprisingly ok with making a run at Rose and then trying to sign a Center like Pau, Dwight or Horford.
Melo is heading into the last 2 years of his all star level of play in my opinion, so if you have a chance to put together a team with Porzingis, Howard or Gasol and Rose around him and you haven't lost draft picks like KP, Grant or future picks in the process, I think it's worth the risk. When Roses contract expires in a year you can make a run for Westbrook.
