Why is number 8 Kobe, so much cooler than number 24 Kobe?

ya but #8 Kobe couldn't win without Shaq. The "swagger" you are talking about doesn't win titles. Its the intensity and business-like attitude like the Black Mamba #24 has now. And 24 is older and smarter. He cant jump outta the gym like he did when he was younger, and now he takes what the defense gives him and he improved defensively.
