i) It could be argued that D'Angelo has more upside (if only because of his playmaking/passing)
ii) I think Booker is better now simply because he utilizes his strengths on a more consistent basis, can break down defenses more regularly, a bigger threat as a scorer (not because he averages more points) and plays better defense (whereas D'Angelo's defensive awareness and effort can be extremely poor at times). D'Angelo's play is far too erratic where he often goes missing if things aren't going his way. Booker makes things go his way.
iii) He put up 39 points on 29 shots, which I'd say is pretty efficient given the circumstances
As soon as y'all get a competent guard to run the point and move D'Angelo to the 2 spot, only then do I believe that he'll start to look better on a more consistent basis. Simply because he ain't a PG.
I agree Booker utilizes his strengths and attacks mostly looking to score. But he is not tasked with running a team. He has a ultra green light and plays LOT of minutes. Russell is learning how to play winning basketball and is being held accountable.
I have not seen Booker do anything that Russell can't. Booker is not an exceptional athlete (slightly more explosive then Russell). From what I have seen he doesn't have more capability to break down defenses, he is just more aggressive and has a scorer's mentality. How is Booker averaging 20 PPG with a PER under 15?
Neither are good defenders, but I would add the caveat that Russell has a tougher match up every night at PG and still has a better DWS and DBPM. Booker is guarding one of the weakest positions in the league in terms of star power.
As for whether he is a 2 or a 1: the Lakers are committed to converting him to a 1. Curry, Westbrook, Harden, etc have all showed this is possible. Let the man learn how to do it. The game will slow down for him and his size will give him advantages at the 1.
At worst Russell and Booker should be viewed on equal footing. However, at this point Russell's stats are better in nearly ever category while still learning a new position. Yet people are saying Booker is better.
