If you want to be like the Spurs you need three veterans guys all of whom can both pass and shoot. Also, they need to be old enough to be willing to take massive discounts but not so old so that their productivity is massively diminished. Oh yeah, a coach and veteran players with the experience of three championships behind them.
If the Celtics new Big Three had been willing to take larger discounts and Garnett hadn't become a shell of himself so quickly and Allen hadn't left and Ainge had done a better job of drafting/acquiring useful young talent that Rivers could then feel comfortable giving large minutes to in order to rest the vets, we could have been the Spurs East.
