Mentally weak?! Did you notice he's a freaking freshman Hat? The guy's body may have matured, but his mind clearly hasn't (as is the case with most 18-19 year old males). I know you've been at this a long time, but surely you have seen people improve and develop over the years? A "mindset" is something that can grow, develop, and change over time. Give the guy a year or two before writing his future. Just b/c he's not going to be 1 and done like everyone thought doesn't mean he's going to be a terrible player.
