What a joke, you think Bill Self ever maximized the top recruits he did have like Andrew Wiggins, Josh Selby, Josh Jackson, Billy Preston, Quentin Grimes, Cheick Diallo, Cliff Alexander, etc.
Your list of top 20 HS recruit busts is impressive. Self is partly to blame for not putting those guys in the best position to succeed.
Self is one of the best coaches of all time but his expertise lies in getting transfers to buy in and managing experienced rosterd. He's been awful coaching elite freshmen so not sure why you think his results would be better if he had more of them.
Duke certainly hasn't underachieved in the OAD era, would be nice to have another FF or title but its a single elimination tournament. We've produced 7 Freshman All-Americans, won the ACC or ACCT 3 times, been to 4 Elite 8s 2 Final 4s and won a Natty in 7 year (no tourney in 2020).
