I'm more of a Cooney supporter than "hater", but when he's playing like this he should be sitting. We have Howard and Joseph on the bench, no reason to give them 5 straight minutes and see what they do, if they fail, put Cooney back in, he still doesn't have it, go with the other guy Howard or Joseph who didn't play the first time and use some sort of rotation, throw crap against the wall and see what sticks, it can't be worse than what is happening.
Like I said earlier, Joseph actually looked like a point guard bringing the ball up and G looked like a scorer when he wasn't bringing the ball up, isn't that what we want?
