A lot of work to do
From the Oladipo example, he needs to display a controlled athletic game and improved handle in his second year and an outside shot in his third. Without a jump shot, he won't be drafted.
He has a twist in his upper body as he shoots. He compensates with his wrist as he releases the ball. It makes for an inconsistent shot. He needs to break that habit and put up 250 shots per day shooting with the correct form in the off season.
