Kinda like what FAN said..... Shane is playing great ball right now so he is gonna see a bulk of the minutes at the 4.
Nino played bad vs OU and he is in a little funk right now.
I hope Nino starts playing better, but even if he does, at this point you have to give Shane a 2 to 1 adv in the minutes. Diaz just isnt ready to play meaningful minutes, so that is why Nino playing decent ball is important for this team
