The idea of a Duncan & Amare front-court is mouth-watering. But as you say, it seems unlikely the Suns will agree to trade him to the Spurs. Besides, as you say, who can the Spurs give up in return to make this trade worthwhile for the Suns? Ironically, the Big Three have been doing OK so far: Manu is healthier than he had been for years and with a bit more game time under his belt could be on fire come playoff time; Duncan is having an MVP year and anyways should never be traded full stop; and Parker - well, he's slowed down this year, but he's clearly injured and I think he has too much upside to consider trading and he's still fairly young. Which only leaves the Spurs possibly giving up RJ with his fat contract and perhaps another good player such as Mason. Not sure what works financially, though.. But despite Amare being one of the arch-rivals of the Spurs in years past, I think it's def worth looking at. He has the nastiness, toughness down low that Duncan and the Spurs need right now
