The Lakers ended the same way. Most dynasties do. It just gets harder and harder to replenish the role players with very low draft picks, salaries filling up the luxury tax, and no one wanting to deal with you. Houston added Barkley and Pippen; Los Angeles added Malone and Payton.
In the second case, it almost worked. But even with Kobe and Shaq still in their primes, it was the decaying roster around them. We sure look like the 2003 Lakers right now, with Slava Medvedenko and Brian Cook out there, except ours are graceless old farts.
This was always the issue. We knew this team had to be retooled in a significant way LAST year, but managed to win the championship, anyway. Then this summer was pegged as the reload, since so many contracts come off the books (although we don't clear any cap space), and we'd cross our fingers and hope savvy and willpower would get us a back-to-back. It's looking bleak at the moment, but hopefully we can turn it around.
Meanwhile, the future... Splitter and Mahinmi will have very little seasoning next year, and we can't expect big returns for them until another two or three years down the line. Any rookies we might draft and, conceivably, are any good at all, will take just as long, unless we draft a good domestic player, which has never happened before. We can sign James Jones and tinker with the roster, but I expect many of the pieces we're depending on this season to still be in place. In short, there are no quick fixes. I'd expect them to go for V-Span, simply because there is no better option, although apparently he's an ass. Otherwise, we'll grind another year with too many old players and a small passel of way-too-young players.
