Ah, the Michael Jordan/Phil Jackson Effect. The coach gets the credit for the talents of the player. The Spurs would have done just as well with any number of other coaches.
I definitely would have to agree on that. I think the same goes for coaches like Pat Riley, Scotty Bowman or even Casey Stengel. All of them were great in their own way, but all 3 teams had massive amounts of great talents on thier rosters at any given moment.
