The anime for Slam Dunk ran for 101 episodes and made it through about two thirds of the manga. According to Wikipedia, it also had good ratings and sold reasonably well. The anime and manga have both ranked as one of the top series of all time according to multiple sources.
It seems strange, then, that the anime would abruptly end right before the climax of the manga story. I could see this happening if the series wasn't making money, but normally they'd cancel such a series long before 101 episodes, and it's hard to imagine that it was losing money given the commercial and critical success.
Is there any stated or likely reason why the anime ended at 101 episodes without concluding the story?
