He would have had a higher ceiling relative to where he was drafted because (a) probably not as good a basketball player at 19 as he was at 22 so his net present value would have been based more on future value (and ceiling) than what he was capable immediately after being drafted, and (b) he would have gone later in the draft. Compared to the 22 year olds that would have been available when he would have been drafted, he ABSOLUTELY would have had a higher ceiling than those older guys (like Nolan Smith) who may have been drafted around there... if those players were three years more mature, three years more of college AND had as much potential for growth as he did, they wouldn't have slid to the spot where a hypothetical teenage Dame would have been drafted.
