I do think he's dumb for running a read and react offensive system - it's great for creating NBA prospects and less so for actually scoring points in the college game.
I think it sort of works if you have elite, NBA one-and-done prospect guard who can shoot or an experienced guard who has drilled in the system for ages (Isaiah Taylor was in his first season in the system and Javan Felix was.... limited). You also need shooters off the ball.
I disagree with the choice of the system - in the college game it reduces your margin for error because it requires you to either recruit at an insanely high level or develop across multiple years and then hit the pot of gold in your tourney run once every 3-4 years.
It also requires you to consistently roll out an elite defense which Shaka has done so far at Texas so I'll assume for a second he can continue to maintain that
This season with Coleman and his year in the system on ball, Long, Roach, (fingers crossed) AJ1, Febres?, and Osetkowski spacing him with an athletic rim runner in Sims he may finally (again knock on wood) have the offensive personnel to make his system work and Texas *could* have a big season.
But even there I wish he didn't run this system - it gives him no margin for error if those "shooters" don't turn out be league average or if Coleman stops hitting long twos at an unsustainable rate etc.
