Actually I disagree with both of you. Pop believes that Rasho would not be effective defensively because there is no one for him to cover that matches up. The notion that Rasho hurts the team offensively is untrue. The penetration he helps to create for Tony and the screens he sets for Manu and Finley are valuable. Just because he isn't shooting does not mean he hurts the team offensively. As for getting in Tim's way on the offenisve end- that is Nazr's problem, not Rasho's.
I also think that Finley is outplaying Horry and that is why we are seeing even more small ball.
