I'm not disagreeing with you, but it seems relevant to note that Keyonte's off-the-dribble 3pt game is well beyond Mitchell's at the same age. That one skill can crack open a pretty devastating path of development.Keyonte this season is SOOOOO far from rookie Mitchell. If he ever becomes even close then it will be a great result for us. Mitchell becoming a legit top 15 player and a guy who can handle a scoring load semi efficiently at his size is a huge outlier. I don't think Key will ever get close.
I know you said 'assuming massive development' but even that feels like it is giving too much credit to Keyonte.
