Blowing up the Suns can beat the Spurs....we can outlast them. I dont forsee us getting past the Spurs in the next couple years so why not cash in chips now and build around Amare/Barbosa/Diaw?
Because there is no reason to believe it will work. None.
The window of opportunity is usually open very briefly. 15 years ago the Suns were ever so close to having a championship. A few breaks and it might have gone another way. But it did not take long to destroy the team and send the team back to mediocrity.
RIGHT NOW, the Suns have the best point guard in the NBA and two other all stars, an all NBA defensive player, and the sixth man of the year. There is no assurance that Nash will last more than a couple of years, Bell is getting older and KT is already on borrowed time.
Waiting until Duncan is not effective kills the rest of the decade. No thank you.
=============================================
On the other hand, I think a couple of minor pieces might be enough. I'd like to add mone more physical big who can keep Duncan out of the paint for a few minutes when KT is not on the floor. In the draft thread I've suggested someone like Chris Richard who might not play much the rest of the year, but he's really long (9' 2.5" standing reach) and really strong. He is not expected to go until late 2nd round. He has no offense, but did better than most in defending Oden in the finals.
My other big hope is to get another wing who plays tough defense and shoots better than Jones. To beat the Spurs, the Suns have to hit their open shots and be able to finish strong at the basket.
