Embiid's numbers are underwhelming, and, as I said before, the number of big men who had long careers after developing foot problems is pretty short. In fact, while I am sure there are some, I can't think of any off the top of my head. Embiid is a 7' athlete with some athleticism, but nothing here justified a draft pick this high. And he has a back problem to boot.
And it wasn't like Kansas was dominant with both Wiggins and Embiid on the court together. They were a very good team, but there were a lot of very good players on the team in addition to those two. An Okafor or even a Thabeet, in their final year at UConn, would have lost 3-4 games with a supporting cast like the one Embiid had. Not 10.
