Ultimately the head coach is to blame but since he clearly is a good coach, in place, familiar with the existing program then he is a good choice to fix it. Some teams overachieve others underachieve, happens every year, why would you think any program is immune, it is predictable in D1 basketball. Reasons it happened to my Sooners this year, I generally lean toward player leadership/ team chemistry with a dose of talent lacking at some positions. It is not imo x's and o's. I would expect one to three players to move on after the season plus Trae. I really feel Lon did most of the right things but it's difficult to predict how a person reacts when they are not the big dog, do they work harder or grow bitter. Lon brings them in, he needs to avoid mistakes next go round.
