If you think his numbers are "inflated" because of his minutes than look at his advanced stats and it will give you a better idea of how he is doing! I made a list of wing players who got more than 1000 minutes this season and ranked them based on AST%, REB% and FTr(Alec is also on that list!).
I don't know how you define "exceptionally well" but his passing and playmaking is elite in my book(compared to wings!). His rebounding ain't elite but he is
above average and it has nothing to do with the minutes he gets. I agree with the defensiv part but really who is an above average defender on this team? We just have Derrick who is above average and that's it. And more than individual defensive guys this team needs a coach who can implant TEAM DEFENSE. Like coach Clifford did in Charlotte. And he ain't getting to the line like an elite wing but again he is above average in that depature as well.
Why is him passing to outside shooters a problem? It's not like he is standing on the perimeter and passing to his left or his right and says "shoot it". There are really two possibilitys. He can drive to the basket or he can play a PnR with one of our bigs.
When he drives to the basket he can either dish or kick it to the outside. And defenses don't allow a drive and dish so much in the NBA. So it is up to the ball handler to make the right read. If the dish is not there than he have to find the open man at the perimeter and that's not a bad thing at all because it's a wide open shot most of the times.
When he runs a PnR with either Enes or Derrick there are the similar options. You find the roll(Derrick), the pop(Enes) or the outside shot. If the defense does not allow you the roll/pop than you gotta kick it out. And that wouldn't be a bad thing either.
He is doing a good job when he drives to the basket. I really don't remember situations where he didn't dish the ball in favor of an outside shot but he could do a better job in PnR situatins with Derrick but that really isn't just Gordon's problem.
And I totally disagree with your second part I don't see him as a top 2 scoring option on a team with quality players(he would be the 3rd or 4th opion) but I would still let him handle the ball and create for others even with quality players!
