He will continue to shoot at a high rate, because as mentioned already his passing is terrible. His game scores have been low which suggest that he has not been a great fit in your gameplans, and he doesn't seem to be able to do much besides shoot and grab a few boards each game.
You can either use his limited skillset in situations that warrant it or grab a more balanced SF. They can probably be found for under 20k at 3-3.5k salary. Because you're not gonna stop him from going rover. ;)
