No he's not. This isn't RR. You don't have to be a complete homer.
Any of KyKy, DJ, and DA could've scored 40 on that Pendleton Co. team. They had a losing overall record after he got hurt, which goes to show that the offense was completely ran through him. He had to drop 40 for his team to even have a chance. Anyone with a lick of talent could score 40 against the talent he played against and the offensive system he was in. His teammates clearly weren't good.
But I'm not arguing his talent, obviously he is good. We're arguing the "he's as good as anyone else coming in" part. That isn't even remotely true and you know it. If he were, then he'd be a 5* McDAA and projected in the '20 NBA draft like a few others.
