Knicks should be on this list.
My theory:
Knicks have a nice break out season. Melo is back a top 10 player.
Things dont work out with CP3 and Harden in Houston. Plus Goldenstates winning the West regardless.
Knicks will get JR to return with Lebron. and CP3 follows (really I dont even think they'd need CP3 but why not

)
If possible Knicks will have a nice versatile and virtually unbeatable line up:
CP3. Frank (hoping he develops into a nice 2 way guard)
JR Smith, Tim Hardaway, Lee or Dotson and Frank can also play the 2 guard
Melo or Bron (can play both position) Maybe Tim Hardaway Jr too
Bron at PF naturally, Kristaps PF (if Bron at 3) Melo (PF if Bron at 3 and Kristaps at Center)
Or Kristaps finally ready to be Center, Hernangomez as backup
Lebron to NYC would be the biggest thing to happen in the NBA since I dont know when. New York is the Mecca
