It's that kind of attitude that created the Clippers. In order to learn effort, grit and pride, an NBA player needs to feel that they have a chance to win it all, that's why the Jazz play to win even if it limits the time for the rookies.
And i'm not ready to declare that the 'dog' Al will never learn new tricks. Malone learned to shoot mid range shots, and improved his free throw percentage, Jason Kidd learned to shoot the three at the end of his career. Al talks about learning to pass the ball, and assuming he isn't just saying what we want to hear, I think he's working on it. It may take a few years, but he'll probably get it eventually.
As to whether he does it with the Jazz, I agree with an earlier poster that we lose Al because they don't want to max his contract, not because the Jazz don't appreciate his value.
