Good kid, can score in many ways, plays in the flow of the game, off the charts intelligence. Has a clear NBA position at small forward. Not an elite athlete, but elite enough.
What more could you want?
Defense
+1. Defense might get better with experience but especially a better body. And getting a pro is not easy or possible for some people no matter what they do. Look at jared dudlley, scal etc
Wiggins imo is the safest bet. Embiid also more on the safe side with higher upside due to playing the center position
Parker is just smarter than Wiggins. Looking at them play, it just seems clear that Parker has a better understanding for the game than Wiggins does. That's going to make him a better NBA player. We don't talk about BBIQ too much, but the fact is that the elite players: LeBron, KD, Dwayner Wade (as much as I HATE that guy) Rondo, CP3 - are all super duper smart players.
He also has that super long wingspan. I'm sure that Parker could figure out elite defense. Defense is mostly hustle (as proof of this, I can play defense and help my team in pick-up, even though I can barely hit a lay-up).
No, defense is not mostly hustle. Lack of hustle will waste talent, but guys like Lebron, Howard, or even Bradley aren't excellent defenders just due to hustle. They are excellent due to their quickness. TA is the same. Artest was great due to his hands and his strength. Battier is more of a thinking man's defender. The mental part of defense is as valuable as the effort, so Parker could manage that.
When you are a top tier team, everyone is giving a high level of effort, so the talent and skill differences in defense will matter.
I mean, will trying harder stop AI from breaking your ankles?
Pickup is irrelevant because you are dealing with guys who aren't trying hard and who aren't being coached. You can't apply that to NBA competition.
