I think Mullin answered that fairly well in that Newsday article last month. If they all get better, then I don't expect much to change unless games are close
For those who didn't see it, here's the link and the excerpt about coaching delegation

Delegation observations
Mullin, too, has become the target of some snark as St. John’s losses mounted this season. ESPN commentator Jeff Goodman isn’t the first to comment on how animated 26-year-old assistant Greg St. Jean is on the sideline and in huddles, but he has made a point of calling the Red Storm St. Jean’s team.
It’s true Mullin has given significant responsibility to St. Jean, who is the son of Garry St. Jean, who coached Mullin at Golden State and preceded him there as general manager. Mullin regards the young St. Jean as a rising coaching prodigy, but there’s no question about who is running St. John’s program.

Mullin cites the great Larry Bird, his former coach with the Indiana Pacers and his teammate on the 1992 U.S. Olympic Dream Team, as the model for his collaborative approach. “The thing I loved about Larry — obviously, I looked up to him and his great playing career — is that he had [assistants] Rick Carlisle and Dick Harter, an offensive guy and a defensive guy,” Mullin said. “Larry oversaw both.”
The media would give him flak, Mullin said. “ ‘Rick’s doing that.’ The more successful we got, he didn’t waver. He wasn’t going to go, ‘Oh, I’ve got to run it.’ Larry was confident in himself. He was comfortable in his own skin.”
At times, Mullin sits in the huddle and directs his players, but he also has given St. Jean a prominent role in running practice and providing sideline instruction during games. That sometimes includes diagramming plays.
“Whatever we do, I tell him what I want written up, and he writes it up,” Mullin said.
“You do most of your preparation in practice. You can’t give these kids too much in a timeout. If you give them one thing and they remember it, you’re a genius.”
Mullin described the notion that Bird — and by extension himself — doesn’t know how to diagram a play as “comical,” and added that basketball really comes down to finding a way to put the ball in the basket.
“Larry would say, ‘Are you going to make a shot or what?’ That’s what it was. Period. Now, getting good looks, moving the ball, that’s the details you work on.
“To me, it’s like, Wow, they [media] really don’t know what happens in a basketball setting, do they? They think that a 30-second timeout is coaching. If you don’t know what you’re running and you’ve got to diagram it, you’re screwed.”
