It will be interesting to see what kind of introspection the offseason brings for James. I don't blame him at all for lacking any right now. The failure is too raw. But there is a reason Kobe Bryant has 5 NBA Championships, and it's not just that he played with Shaquille O'Neal for three of them. It's because he was completely obsessed with studying game tape of older players and trying to incorporate their brilliance into his own game. When Bryant came into the league, all he could do was go to the basket. So he worked hard all summer and shot thousands of jumpers a day until he had a mid-range game. Then he developed a credible 3-point shot. Then he worked on playing with his back to the basket. In many ways, he was just copying Jordan's evolution, plagiarizing it even, but it's tough to knock him too much for copying Jordan note-for-note. Why wouldn't you want steal the work habits of the greatest guard of all time?
Great players evolve, especially when they are tested. Magic Johnson learned to become a better outside shooter, and developed a baby-sky hook to give him a post game. Tim Duncan developed a robotic, mechanical and fabulously consistent bank shot turnaround. Karl Malone turned into a very good jump shooter coming off the pick and roll. Shaq developed an ugly but effective jump hook and became a very good passer out of double teams. Larry Bird became a better passer and pretty decent defender as his career went on, before injuries derailed it. There are countless other examples.
LeBron has already fixed some holes in his game. He became a good defensive player, having realized after playing next to Bryant in Olympics that he wasn't working hard enough. And he's a better outside shooter than he used to be, although he's more streaky than good. But he's still needs to evolve. He needs a go-to move that will restore his confidence in moments when it's been shaken. I suspect -- actually I hope -- he will find one.
