Phil Jackson has thirteen rings, two as a player. (He recently tweeted to that effect, per Katie C.)
Eric,
Phil Jackson, as Pat Riley and Red Auerbach, had the ability to successfully lead teams of All-Stars. That shouldn't be taken lightly.
Interesting that you lump PJ with those two because both of them went on to become excellent GM's... sort undercuts your basic argument.
I didn't follow Riley's or PJ's teams but I did Auerbach's and I don't think anyone would disagree that he was very much the architect of the Celtic teams before he was officially the GM... in fact, I don't think they had GMs who were responsible for assembling teams back in those days. Red Holzman (contempory of Auerback) was regarded as the architect of the Knicks and whenever the teams were discussed, the coaches were talked about as though they put the teams together. Actually, the first GM I recall hearing about was Auerbach, after he turned the coaching duties over to Bill Russell.
When there were discussions about PGs for the Bulls was it said that Jerry Krause didn't like traditional NBA PGs? No, PJ was the one that understood that such did not have a role in the triangle offense.
When Jackson moved to the Lakers was the talk in basketball circles about how he was blessed to get Shaq? No, the talk was about what a bad fit Shaq was for the triangle offense - you might recall that the Bulls typically rotated a number of lesser centers through that slot. It was Phil who assured everyone that Shaq would fit it perfectly.
It was only those widespread discussions that I read about but in watching his teams I was always impressed with the way he took players on the downhill side of their careers and made them useful pieces on his teams. Remember Ron Harper? He was the first one I remember because I wondered what in the devil Phil had in mind for him.
So, yeah, Phil has had great players to coach but he was a master at recognizing the talents in all kinds of players that would be valuable to his teams.
Similarly, in retrospect, you could say that Auerbach rode to fame on the coattails of his all-star players but at the time it looked more like it was Red finding the right role for the guy, allowing him to blossom as an all star.
