Dude, there's just no way a player with Sochan's physical tools isn't a draft pick at all. He's got the height, physical frame, and basic qualities to be a draft prospect, and that's not very arguable (which exactly of his metrics is not even "second-rounder" quality?).
Jeremy is about the billionth young player drafted for physical tools with the ever-pressing asterisk of "if he ever learns to shoot......", except he spectacularly failed at that portion, much more so than similar prospects who at least learn to be serviceable at it over time. Does that mean none of the prospects had business being drafted? Of course not - it just means you can't predict human progress or development in a linear, objective, or conclusive fashion.
You should also factor in that his looking worse this season isn't only his play in a vacuum -- the team around him has elevated, the expectations are higher, leashes are shorter and timelines accelerated. He could absolutely contribute to a team like last night's Atlanta, or tomorrow's Washington teams.
