Can always count on the BY for recency bias.
Diarra is playing because he brings aggressive D. To his credit, through constant effort, Diarra consistently brings the same results every time he steps on the court. Dan Hurley and everyone knows what they’re getting when he enters a game.
Joey C is the opposite, when he’s on he brings scintillating offense to the game. Offense is a skill set that can’t be elevated through effort, by shooting “harder”. It’s not as consistent.
So, yeah when Joey C is off then more of his minutes should go to Diarra.
But when Joey is ON, there’s no debate. Joey plays, Diarra sits. A hot shooter trumps D every time. EVERY TIME. It can flip a close game into a runaway rout in a matter of minutes. it comes and goes. Must ride it when it’s hot.
