8. Vladimir Radmanovic
When the Lakers signed the sharp-shooting big man out of Serbia there were actually high expectations that he could come in and make a major impact for them as a starter at the time. He had some success with the Seattle SuperSonics before coming to the purple and gold as a sixth man scorer off the bench but he was eager for a bigger role elsewhere.
Before the 2007 season, he was expected to re-sign with the other team in Los Angeles, but he was ultimately convinced to come to Lakers because they promised him a starting role.
However, Vlad Rad never lived up to his lofty expectations as a Laker and he never seemed to take basketball serious enough during his time in Los Angeles. In 2007, he missed an extended portion of the season because of a snowboarding accident that he initially lied to the team about and he ended up having to pay a $500,000 fine.
He was eventually traded to the Bobcats for Adam Morrison and Shannon Brown, so at least the Lakers got an exciting role player in return for him.
