Sean May
Sean May went from one of the most unstoppable players in college basketball, at North Carolina, to an injury-riddled bust in the NBA. For a player who was already both huge and hefty, the string of injuries he suffered shortly after arriving in the NBA couldn’t have been more disastrous. The microfracture surgery he had on his knee caused him to miss 18 months of getting anywhere near playing shape.
At one point, the Sacramento Kings even put an incentive clause in May’s contract, which would pay him $100,000 if he made it to a respectable playing weight (which he did achieve). Still, he was never the same player after that. His NBA career soon ended, and he bounced (figuratively or literally) to France, where he finished his basketball career.
