Get Rondo out of there before Miller purposefully tries to take him out.
I don't mind Rondo playing a lot of minutes, I think its good for his confidence going forward... plus, our offense stops running when he's out 
I have no problem with Rondo's minutes. Play the little guy 40 a game for all I care, he's got an endless motor.
My concern is a dirty player like Miller, who already has a history with Rondo, might not like getting embarrassed on his home court and decide to take out the littlest guy on the floor who whacked him hard earlier this year.
