Well, let a long time Laker fan offer up a bit of history....
Back in 1970, there were three new teams coming to the NBA, Buffalo Braves, Cleveland Cavaliers, and the Portland Trailblazers. Every team in the league had to make 1 player available in the expansion draft. Chick Hearn conjectured that the Lakers might want to keep their new talent, and make Elgin Baylor available, or perhaps even Jerry West. They didn't, and the young guard we lost, Johnny Egan, never went anywhere after the expansion draft, but the idea to go for the future was there.
What trade value does Shaq have now? Little or none. People who think the Lakers would have won more les with him are speculating, and I don't like the odds we would have faced. Even if the Lakers had, we would be horrible right now, with no future in sight.
Face it, for the latter end of the Shaq/Kobe era, it was all about those two guys. The league had adjusted to us. Sacramento came close in 2002, but not close enough. Spurs beat us fair and square in 2003. Malone and Payton got us to the finals in 2004, but Karl wouldn't be back for another try, even if we kept Shaq and Kobe.
Now, we are a multi-talented team, anyone can become the go-to guy. Anyone who says Kobe can't win without Shaq is in denial, and talking smack. Look at the Lakers history, we always rebuild. We just did it quicker than expected and became the best in the west again, and a lot of fans don't like that!
Kobe can and will wn without Shaq, the only question is when. I say soon.
