Once again look at how the 4 Out Look helps the Knicks and makes it tough to defend:

Pic 1 you can see that Melo is faster than PF and C that would have to guard him in SPACE! Look at all the targets Melo has with Lee, Kuz in the Corners and Rose roaming.
Pic 2 Noah's man Lopez doesn't want to come out too far on this PnR with Rose cuz he knows he can't stay with Rose and plus Rose is not a Jump shooter, but Rose is too fast with that much space he can't be stopped. Defenders don't want to leave Melo or Lee and LT is right under the basket.
Pic 3 Melo is trailing and Gibson knows it so he's kind of stuck. Rose can attack his defender if the ball is passed with RoLo distracted by the PnR. LT is in a great spot in the Corner.
All of this is IMO better than when this team is in Triangle and we are pretty much looking for Post Ups by Melo or KP and the defense can focus on stopping Melo and the opposing Center can get set in the paint to defend the basket. Help defenders are closer to being able to help and the paint is clogged so our guards like Rose can't drive as easily.
