One possible, and really unlikely win, considering the opponent, does not justify interfering with how the coach manages a team for the long haul. I have no problem with Kobe pointing out the issue, if he had left it that. Instead he demanded that his coach immediately throw his teammate under a bus, and likely make life that much more difficult for his coach, unnecessarily. You can make it out to be reasonable, but it wasn't. He crossed a line, as he has typically crossed the line.
My bias is not preconceived. I swear I have the utmost respect for any other Laker legend, albeit a little begrudgingly. My bias is formed from instances like this one. But it only makes seeing him lose that much more enjoyable, so what the he'll - he's gotta be Kobe.
