didn't McDonald's and Sprite drop him for a couple of years after Colorado? I don't remember what Nike did. He only recently started getting them back. And I doubt it was at the same $$$ as before.
They all dropped him when it broke out in the summer of 2003. Addidas was sponsoring Kobe and dropped him then Nike scooped him up the following summer of '04. He rocked the Hauraches 2K4s that year. But Sprite/Coca Cola came back strong by the '07 season. And the rest were ALL on board by the end of the championship loss in 2008. He definitely lost no less then $100 million in that 5-6 year span.
