Consider Eric Bledsoe
Eric Bledsoe was a young guard for the Clippers that was in line to be their starting point guard for years to come. He was traded shortly after the Clippers acquired CP3 because the Clippers knew he was too talented to come off of the bench and play sparingly with CP3.
Bledsoe could have stayed in Los Angeles and played with guys like Blake Griffin and DeAndre Jordan, who would have been with the Clippers anyways, as they were both drafted by the team. Instead, Bledsoe was traded to the Suns, who have made a habit of trading away almost any talent that comes their way recently, with the exception of Bledsoe.
His career could be tremendously better if David Stern didn’t decide to veto the trade where CP3 landed with the Lakers.
