15. Martell Webster
It’s hard to call a guy who has carved out a role on a playoff team a bust, but the fact that Webster was selected as a high-lottery pick out of high school suggests expectations much greater than that of a rotation piece. Taken by the Portland Trail Blazers with the sixth pick in the 2005 NBA Draft, Webster is one of the last high schoolers to be taken with a lottery pick, and while he has proven to be a serviceable NBAer, he has hardly performed at the level expected out of a top-6 pick in the draft. Over ten NBA seasons, Webster has averaged 8.7 points and 3.1 rebounds per game. He was always a solid role player and pretty reliable too, but with only 41 players to chose from – Webster inevitably takes the last spot on this list.
