great thread and great posts Broadway (has your name always been Broadway?).
i think there's way too much emphasis on the triangle offense as an end-all, be-all. of course there will be tweaking depending on what players you have at what position, but the fact remains the offense is a series of passing and cutting, dictated by the defense.
I believe Phil envisioned Bargnani, JR, Iman and Jose being a large part of the triangle's success in NYC, with all of them hurt at the start of the season, and Sammy not getting it done at the tip of the 'angle (or having a clue), plan B took effect much sooner than later. I'm sure clearing the roster was a contingency plan that reared it's ugly head as injuries filled the bench and d-leaguers the floor.
the future of PJ's Knicks will count on 2-way players with basketball smarts, not the street players, not the high-priced 1-man wrecking crew, but a menagerie of hand-picked high bball IQ players in the $8M-$12M range, give or take a couple mill.
This can and will round out the roster, allowing Melo to be in the flow of good teammates, to not be double teamed, to allow ball movement, player movement, passing, cutting, open 3's, pick n rolls, etc. , and ultimately, finding the open man who can hit the open shot from where the triangle designates.
i'm pretty sure i'm agreeing with all you said, Bway, it's a matter of having the right team players. PJ has his work cut out for him, but at least he's looking to have a clean slate to fill, and that is a very good thing.
