Robert Traylor, Bucks (1998)
For a brief moment during the 1998 NBA Draft, the Dallas Mavericks passed on taking Dirk Nowitzki (and Paul Pierce), and instead selected Robert “Tractor” Traylor with the sixth overall pick. But the Mavericks quickly traded Traylor for the rights to Nowitzki, as well as Pat Garrity, on draft night. Coincidentally, they subsequently used Garrity as part of a deal to bring Steve Nash to Dallas. Meanwhile, Traylor lasted just three seasons in Milwaukee, before they traded him away. It was later revealed that he had a heart condition, which likely led to some of his conditioning and weight problems.
