I'd still pick Wiggins over Parker, but right now I'd take Embiid over both.
Parker is fantastic, but he's doing all that against college competition. If a raw Wiggins can shut him down, imagine what grown men can do to him.
Wiggins shows a real NBA skill, defense, and lots of potential at everything else. The kid doesn't lack confidence, he took the decision to guard Parker in his second NCAA game, against what Coach Self told him to do. He was benched because of foul trouble in the first half, then he took over the game. That's a winner in my book.
Both Parker and Wiggins will be great players, but if Parker is that good, then Wiggins is already an elite defender.
Embiid, on the other hand, seems like a generational talent at the center position. He could be a bust, and the other kids might be better in the end, but if you have the chance to pick Embiid, you have to do it.
And I still think we won't get a chance to pick in the top 3.
