Good post, agree with this a lot.
The way this year has unfolded [and some of the criticism of JB from informed perspectives has come out], it reminds me a lot of something that I encounter in consulting, in organizations that have an executive or owner near the end of their career. These guys have been successful their entire lives, but things often slip late in terms of their performance. They cut corners, they're not quite as comprehensive in their analysis and get sloppier with their critical thinking because they are so confident in their experiential know-how, etc. Things slip, performance decreases, but still the dysfunction continues. In many of these cases, the very attributes / stubbornness that got them there and brought them tons of earlier success now works against them--they can't see the forest through the trees and often can't change, or they are at a point in their careers where they just don't have the willingness / capacity to dig in and do the heavy lifting anymore.
In some cases, others around them have to manage around their increasingly subpar performance that stems from their behavior, because they are the owner, a highly respected executive, etc. I think we're seeing some of that here.
And I agree 100% that JB has been doing his job exceptionally well for decades. We have been so lucky to have him. He's been the coach of the program my entire life, and I can't envision Syracuse basketball without him. But I think it is becoming more obvious that for as great of a game coach as he is, he's slipped in other areas of coaching [i.e., recruiting, managing off the court logistics, etc.]. Sad.
