If this is his system, he should keep to it, because he's a top level coach and it has worked for him before.
BUT, there's no use in criticizing a system that prioritizes shooters when the shooters can't shoot well.
It makes no sense. There may very well be no problem with the system at all.
When the players shoot as expected, they beat Florida, Texas, St. John's, Illinois and Kansas. When they can't shoot well, they lose to St. John's, Creighton and Marquette.
So it's not the system.
It's the consistency of the shooters.
