Since this is least favorite and not worst, I'll go with Evan Turner. He is no where near the worst player, not even the current worst player but because CBS loves him so much and plays him to the detriment of our rookies, I'll go ET.
Runners up have to be Vin Baker, Marbury, Joe Johnson, and the end of Rondo was brutal. Watching him half-ass it on defense was excruciating. And then people would gripe about Olynyk's defense because Rondo's man was scoring over him at the rim. Good times. Finally, great guy, skilled player, but I have to throw Bass in there. There is no player I actually disliked seeing in the game more than Bass. 90% was because I knew he wasn't our future so why was CBS playing him so much and the other 10% was his hands.
