Was it year 2 maybe when Oats reassigned the staff during the season and he took over coaching the defense (or something like that?). But yes, at some point this is on him. Like it was with Saban when Tosh couldn't handle it on the football side. But this is shaping up (as of now anyway) to be a big ass learning experience for Oats this season, and I'd expect a big overhaul on and off the court after the season.
