I don't think he jumps Randle, Wiggins or Parker. Embiid is likely going to go in the 5-10 range, which could be good for Charlotte if they think he's a fit for the team.
I've watched every game of all three prospects you mentioned, along with Marcus Smart. Both Randle and Parker are liabilities on defense. And Randle has questions whether his game will transition to the NBA. He won't be able to bully PF's every night like he does in college.
Wiggins has shown very good defense and solid skills in the fastbreak, but really struggles with everything else. His athleticism and hype are the only thing carrying him right now.
Embiid is the complete package. He is a rim protector, a great passer, and has great post moves with a tremendous touch around the rim. He gets compared to Hakeem a LOT, and for good reason. Then when you consider that big men are more valuable, it's very possible that he takes the number 1 spot.
