I think we're seeing more and more "coordinator" positions in college basketball. Obviously, the head coach has final say, but at the power conference level the head coach also has a lot to do outside of X-Os. Here are just a few examples of this "expanded coordinator" role that I've seen.
Pearl's kid at Auburn coordinates their defense. Mike Burgomaster's official title at Auburn includes "offensive coordinator" in it.
Jeff Linder left a head coaching job at Wyoming to handle the offense for Grant McCasland at Texas Tech. The Athletic had a great feature article on him this week.
Luke Murray does a lot of work with UConn's offense.
Hell, Payton Sandfort took over the coaching duties Thursday for Iowa after Fran was ejected. He had the coach's chair in the next timeout huddle.
So I think the "coordinator" role is becoming much more common in the college game.
