Chief coaching has definitely been a problem with this team, but its not Miller, but Ollie who you should be looking to. If Brimah is your biggest complaint, what does that say about the fact that 2 top 80 recruits in Facey and Enoch have actually been worse than Brimah a sub 200 recruit. By this logic, Miller and Ollie should be hammered for not developing properly supposedly talented players "unlike" Brimah who was "unreachable" according to our experts.
Another overlooked thing in the anti Miller and Travis diatribe is confidence. Our big men lately all seem to lack any assertiveness, confidence, or swagger on the court. Not a strength and conditioning problem as Brimah is plenty strong and athletic enough for his size. They play timid and tentative and like they have no sense of understanding where to be and what to do both defensively and offensively. Like it or not Brimah has been our best big man since 2014.
Every team in America including Calipari would love to have a Brimah on their team. The big problem is coaching, developing players, utilizing them correctly, and recruiting over them if need be. How Brimah has not been developed into an NBA first round pick in 4 years is a tragicomedy.
PS: It's the head coach who chooses a system to implement and for Ollie it has been small ball and neglecting the bigs. Calhoun was the exact opposite of this where he sought a balance between the two.
