I guess Cousins is just perfect then. No reason to blame him for anything, like not running back when Noel does and gets easy baskets from hustling down the court.
Those would be on him, but on several of them Cuz was mugged and to the ground on the other end of the floor. No way for him, or anyone, to get back in time from that position.
And its got nothing to do with Cuz. That's just basketball. Any team, any level. If you see a big man show big on a penetrating guard, and then his man get an alley oop behind him that's really not on him, unless the penetrating guard is so offensively inept that the big is not supposed to challenge him.
Watch good defensive teams play and what you'll always see is the forward on that side of the floor step down in to cut off the passing angle.
And actually when you see that, it normally open the corner three, so the forward has to try to spin back and recover if a skip pass is made. At which time the big's job is to get back and remake contact with his big cover, and fight him for a potential board.
Its jsut the way the game flows. By far the best idea is just not to have your guards get blown by in the first place. From there its a cascade failure.
