Here's what it looks like to me...
The Knicks realize that they have all they need in scoring. Their problem is they would get a lead... then blow it the last quarter and a half. Melo and Amare are enough to produce the bulk... then they have secondary scorers in JR, Novak, Felton, and Kidd (3 pointers)
If you notice.... EVERYONE else on the Knicks beside Melo and Amare are strictly role players. ALL OF THEM. And none of the people that they picked up are gonna take any shots away from Melo or Amare.
Kidd... at this point is just a floor general
Felton.... Same as kidd, but can score more
Chandler... Defensive anchor
Shumpert... perimeter defender, but can score and create his own shot
Brewer... Defender who can score at the basket (but not on the outside)
Camby... Defensive anchor for bench (blocks/rebounds) has a good 10 - 15 footer
JR... Shooter off the bench (probably the only player that might step out of their role)
Novak... Outside shooter
Thomas... ummmm
Prigioni... 3rd string pg, just there for assists and creating shots for others
Copeland... another defender
Nobody is gonna step out of their role... they are there to do whatever their specialties are and that's it. And most of them specialize in defense, so there's no conflict with Melo or Amare. So you know what that means. The entire offense is gonna run through those 2... and the rest just need to go play defense
