I don't know if I totally agree with that. He was considered a pretty raw player coming out who needed to develop a shot but has made significant improvements each year, and just averaged 24 per game as a 21-year-old, and improved his 3P% to over 35% this season. I will agree that he's been abysmal defensively for a guy who should be much better than he is in that regard. But young wings who can put up points in bunches will get that contract every time.
Not that I totally disagree, Minn has no choice really. He's still got upside but he's been dismal through his first 3 seasons.
He's been terrible defensively as you mentioned and yes he averaged 24 per game...
but it took him 19 shots per game to get those 24.
He's basically Rudy Gay with more hype at this point. A one way wing who's grossly inefficient.
If Okafor had been fully healthy these last three years I bet his raw stats would be similar, and we all know how Sixers fans view him.
Embiid, on the other hand, has potential through the roof. If he plays 60 games he's in the MVP conversation.
