That's all true and it was the biggest upset of all-time by Vegas' measure, it merits some ridicule, but that team was extremely dependent on the top 4 guys, they had virtually nothing else..their 5th best player was Derek Fisher who had a terrible year IIRC

..
They were one of the worst shooting teams in the league, had no depth whatsoever, and didn't have any notable defensive players, yet still made the Finals based on talent alone, which is why I find negative comparisons to them to be inaccurate..they are actually a pretty great example of where top-tier talent can take you in the NBA..
Take away the 3rd best of those 4 guys + the 2 primary superstars on the team accepting the end of their relationship, escalating in Kobe putting on one of the most selfish displays of basketball you'll ever see, and that's the finished product..still, though, they made it to the Finals, and they went through the Spurs and a good Wolves team, it's not like they were the 2013 Lakers, etc..
