IMO, Phil Jackson hired Fisher for a couple of other reasons, with 3 main points
1- to increase his chances in drawing interest with Durant (UFA this summer)
Along with Westbrook who will be a UFA next summer
2- to help lure Kobe Bryant, which both Phil Jackson and Fisher have said that he had plenty left to contribute and will not retire in their opinions (early in the season or before last years season started)
(later in the season, after he played in MSG already, he announced his retirement, though I do believe that he can contribute and play in the "right team, system, and talent around him" though it would be a much smaller role
3- To run The Triangle and the Triangle alone
(Fisher quickly realized that he could be making much more money as a HC, after watching Steve Kerr make 5m per year on 5year deal, while Fisher was making about 1.5m per season with a vet min contract (which he has said that he thought he could play another 1-2 more seasons and both Westbrook and Durant have given credit to the leadership of Fisher while he was on OKC
When it was apparent that The Knick's will be unable to lure Durant (as they have shown they are far from being a contender)
And Kobe's retirement was later revealed
Then Fisher didn't fully look to run the Triangle, didn't take advice of Phil Jackson's (minions)
He was eventually fired but payed in FULL for the amount that Jackson did not want to even give to Kerr (though after the sale of Clippers, it greatly revealed the value of NYK's and Dolan)
While both Kerr and Walton will use ALL of their own experiences to run other philosophies/systems other than JUST the Triangle
(though they use principles of the Triangle in GS but use it more to space the floor and to PASS rather than to POST up and initiate the OFFENSE to score)
Kerr has played with 2 HOF coaches in both Phil Jackson and Poppavich, along with one season with the Jail Blazers along with many HOF talents with different styles of leadership
Whether it was Jordan/Pippen/Kukoc/Rodman
Duncan, Robinson, Manu, Parker, Steve Smith, Brent Barry, Horry
Rasheed Wallace, a YOUNG ZBO, Pippen, Dale Davis, Damon Stat, Derek Anderson, Shawn Kemp, Bonzi Wells, Petterson (the Kobe stopper)
Well Then there is Thibs who was waiting patiently
And with the rise of the cap these next couple years, it will have an effect on the coaching salaries
With last summers lack of interest, what would Phil Jackson to different other than the Triangle, his presence, along with CA, (only KP is the only difference)
