Geeze, it is difficult to argue here. Lakers have Kobe and Shaq, that's how they won the 3 championships. You need 1-2 punches. Understand? The problem of SF is that he has 2 duties on the team, score and distributing the ball. You can't just trade SF's distribution part while keeping his scoring ability. Since you are trading SF who is an all star, of course you want something similar back. No need to talk more if you want to trade SF for a solid PG only and hope Rox can win with Yao and a bunch of ordinary players.
Really hung up on the two superstar theory aren't you? Has it worked for us so far? Nope. What does work? Having one superstar, and players who are smart enough to defer to them. It's how the Bulls won, it's how the Spurs won, it's how the Rockets won, and suprisingly enough, it's how LA won. You call the Rocket's players "ordinary" but Mobley is capable of scoring 20 a night, as is Jim Jackson. You think bringing in Pierce or McGrady and having them defer to Yao is going to happen? (Well, first, there is no way we bring in those players, but no one seems to grasp that fact.) The solution must involve a solid point guard, we can't compete in the West without one, it's become that obvious.
I don't think there is there are problem between Scoring points and Distributing the ball. Look at Jason Kidd.
