The late Clayton Christensen MAY have had a valid point about Coach K's organization failure to develop and play a deeper bench but I think it is also possible that he (Clayton) was just irritated that his son did not get more playing time when he (the son) was a student-athlete on the Duke basketball team? LOL.Warren is a good example of GOATs with blind spots - he refused to invest in technology stocks for the longest time, said he didn't understand them. I'm guessing that failure to learn and stretch outside his comfort zone cost him tens of billions.
You've undoubtedly heard of Clayton Christensen. He was on a Podcast years ago and described Coach K's short bench as an organizational failure, for the same reasons that have been mentioned by smart folks on this site over the years: fails to develop new talent, creates an over-reliance on starters, doesn't build a flexible and innovative team culture, etc.
I think my disappointment with Jon is that he doesn't seem to be learning and fixing his own blind spots fast enough given expectations at Duke.
I think that, maybe, K also played a short bench because he knew there was a significant drop off in basketball ability once you got down to the 7th, 8th and lower players on the Duke squad and why hurt your chances of winning by playing inferior players. It's true you run the risk of your starters becoming tired as the game goes on but these are relatively young kids in the physical prime of their lives who have been playing basketball and other sports their entire lives. They SHOULD be able to play 35 to 40 minutes a game (and there's a fair amount of standing around during a game) without becoming too tired.
My guess, too, is that it is not that easy to recruit very talented high school players IF you tell them: "come to Duke to play basketball; you won't start or get significant playing minutes but you'll be valuable in practice and may get 5 to 10 minutes of game time, if you perform well". Again, my guess is that many kids, given that option, would decide to go somewhere else where they can play more. I think that is one of the reasons we saw so many transfers after last season.
