To me the things to like about Williams are very similar to Jaden McD. He can create his own shiot, but you don't really want him to. He's not a liability on offense but not really a plus.
Maybe as scoring prospects....Jaden was at least a stocks + rebounds guy which reflected his far superior athletic ability. The thing is, basically none of the offensive appeal with Jaden translated. If you read the scouting reports on him predraft people were in awe of the scoring potential and that was his case as a prospect. What happened in reality is that none of the offensive stuff happened....I would argue he is an offensive liability but certainly not a plus. He's a successful NBA player because of his on ball perimeter defense, didn't see many people saying that predraft. Is Cody Williams a sneaky all NBA level defender? I doubt it.
