These comments are offered as a response to the questions asked above, certainly not as a bashing of SDJ. He only has barely more than 1 -year experience. I have said repeatedly that I think he is on his way to being an excellent player.
Based upon what we have seen thus far in his career (he could of course strengthen elements of his game going forward), SDJ has been most effective as a spot up (stand still) shooter. When the defense is overextended, he has had some success driving into the lane for short jumpers and floaters. Add to this his hutzpah, and his free throw shooting, we see some very positive aspects of his game.
It appears to me that he is much less accomplished at creating opportunities. He doesn't shoot nearly as well on the move, and other than the occasional floater in the lane, he hasn't been able to consistently create his own shot. This far, we have not seen him significantly involved in setting big men up for scoring opportunities (didn't say he never has). Many of his adventures driving into the lane have ended up in turnovers, blocked shots, and/or deflected passes. Because of his size (and since he is not as quick as Anthony), he gets overwhelmed by the defense a fair amount. Often times SDJ with the ball looks anxious, hurried, and harried as though he is in trouble.
With all that said, I think that we are most likely to see SDJ at the point this season because I do not see Mooney trusting a newcomer with the responsibility. Time will tell.
