15. Hakeem Olajuwon
The dream turned into a nightmare for Olajuwon by the time he retired. After spending almost two decades with the Houston Rockets, he moved to the Toronto Raptors for a couple of seasons. But the Nigerian-born basketball legend failed to make any kind of meaningful impression on the team. It was disappointing but after so long of playing at the highest level, it was unsurprising.

The best thing about an old legend joining a new team is that they sell shirts. Cleveland fans probably never thought that Shaquille O’Neal would play for them. It was the same for the Raptors with Olajuwon. However, ‘The Dream’ posted career lows in every category during his time in Toronto. The former MVP became one of the NBA’s most fading players by the time he finally retired.
