So what is the difference between a good scorer or good shooter? I think that there is a point where the stats can be nuked too much.
Eddie House is a good shooter. He can shoot the ball very well, and his range extends to about the half-court line. He's not really a good scorer though, because he really only scores off of open looks someone else finds for him.
LeBron James is an elite scorer, but a pedestrian to mediocre shooter. LeBron can put the ball on the floor and can at any time score from any point on the court, but in pure terms of success rates, LeBron James is not a great or even good jumpshooter.
That's the difference. Gary Payton: Good scorer, average to slightly below shooter.
And I have to disagree with you on the DWest comparison - wow. I've seen the two shoot with my own eyes - maybe not in person, but on TV and Video.
Delonte West is a more consistently successful jumpshooter than Gary Payton. He's very far from the complete scorer Payton was, but in terms of straight jumpshooting, West has better range.
I have a feeling that I need a 1000 word essay for justification on each of my future picks 
Only if I'm paying attention and work is slow, amiright?
