Exactly. Tell a guy who is 6'7 220 went for 15ppg and 5rbg at the highest level of college ball that he has zero chance at the NBA. Particularly one who just went from moderate midrange threat to +50% 3point threat in a year.
Being an excellent outside shooter is the great equalizer in todays game.
He improved his shooting and had stats that were all conference materials, but where is he at on mock draft board even after a huge season? He's not sniffing the second round and that actually might be a good thing for him since he can work out with any team. There's always a chance that a team could take him, but the question isn't whether he's good enough, it's about if he can improve him stock as a player with a 5th year. I don't think he can. I think people are misunderstanding this as a belief that he won't improve as a player, but that's not the case. Improvement doesn't mean his stock goes up, especially as a 5th year player that has had knee issues. I would even argue that his potential as a pro player would actually go down even if he replicates the same great stats next season.
