Does it really matter? 2009 was a long time ago. His defense was always bad and his shooting has fallen off a cliff. This season he couldn't get playing time on a team that desperately needed outside shooting.
Fun fact is that both he and Charlie V are probably going to be bought out this week. They should be arrested for robbery. God bless Joe Dumars. 
the guy is still a great shooter. The Bobcats just suck and couldn't create enough spacing with their other players to properly use him.
if by "great shooter" you mean p--- poor, then i agree.
his numbers this year are really down from his career averages for shooting:
3 pt% career = 40.2%
3 pt% this year = 28.6%
fg% career = 43.2%
fg% this year = 35.6%
this represents a significant drop in the only real skill gordon brings to a team - shooting.
except that you can't compare his percentages this year to anything because they are from limited minutes and a very small sample size.
