Disclaimer: I am no expert on the triangle nor for that matter anything beyond rudimentary practice of the game. The points which stood out for me (though I am not sure getting up the floor quick was a prime need) :
1. The system is not in use in the current NBA....there must be reasons
2. Phil Jackson (with help from Tex Winter) was the last coach to use it ...and be successful with it
3. PJ had Jordan & Pippen & Rodman and Gasol & Kobe & Odom on his two teams
4. Had a pretty good supporting cast with players like Paxson and Kerr in Chic and admittedly lesser in LA
5. Good post play is essential by most in the group
6. Movement without the ball is a must...and of course attention to detail (location)
7. Good passing an absolute
8. These teams took a while before becoming successful practioners (and used experienced bb/high iq players)
9. Point forward (non traditional pg) ...Kobe, Pippen, Jordan, Odom had the ball in their hands quite a bit and initiated
10. I think the ref. to the non-reqt of great indiv. talent pertained to the supporting cast in principle and their athleticism but as I noted the players with the ball in their hands most were anything but it seems.
Seeing as how recent history shows that only 2 teams played this system at a championship level and used some of the best players in history and one coach (and no one else uses it)... gives me pause that in actuality it is a difficult system to perfect and sustain especially with the movement of players from teams in today's NBA.
Our own "big 3" would be JV, Gay and Lowry. JV is raw and with some post skills and an offensive game still in development. I am not Lowry and Gay are great passers or have post games which stand out either...except in a mismatch. DD is pretty much the same. In a nutshell my own sense says our team as constituted would have trouble.
