Kobe Bryant being integral to the Laker's success is absolutely correct. The Laker's made the strategic decision to structure everything around him and it worked well. No doubt that would have failed with a less talented individual.
However, it is important to view his accomplishments in that light. He scored 40+ points in games because the team basically said "Let's have Kobe score 40+ points today". Because of that, his absolute point totals aren't great markers for individual talent.
