If the guys at the end of the bench aren't costing you points when they have to play then that's a net positive. Points are points. They are art of the rotation just as the ISU players are that were being assessed. That's all.
Yes, they are, but you have to weight it correctly, as in almost none. I am about as interested in KU's 6th big man as I am their walk-on. The only reason to include them now is that as an ISU fan they are indistinguishable, which should tell you something. It is always the top few guys that decide things.
