Good post - there is "zero" harm in trying it.
1. He has shown a fade away jumper in the post.
2. He has shown a left hand around the basket
3. He's shown he can take the ball off the dribble on a face up
4. He's shown a good mid range jumper.
5. He's also shown he can pass out of the post
If I were Doc I would at least "try" 2-3 plays for him in the post.
With Sully's IQ and having a little fade away jumper it won't be long before he starts doing up and unders off his pump fake on the fade away...
Free Sully, let him mess around in the post, place KG at the elbows of the base line.
Why not?
