In general, the Kings get killed by the pick and roll. We simply don't defend it in a way that allows our defense to reset. For the most part, the blame goes on whomever our big is on the defensive side. Can anyone remember back to the days of Scott Pollard. He's one of those guys that didn't do any one thing great, but was great at doing a lot of the little things very well. If I can jog anyone's memory of Scott, remember him defending the pick and roll by coming off and pushing the other teams point guard out as far as he could on the floor, thereby defeating the pass to the roller, and giving his team time to make the appropiate switches. The key is, he stopped the ball from moving for a long enough period of time to defeat the purpose of the pick and roll.
The only player I saw on the Kings that did that on a regular basis was Hayes. On occasion it was Thompson, and every once in a while it was Cousins. In fairness, to Thompson, who defendes the pick and roll pretty well, he was seldom the player involved at the top of the key, and was usually the backdoor protector. Because of a breakdown at the beginning of the play, the other team was going to get one of two things. A clear lane to the basket, or a wide open jumpshot. Too many times we want to blame Tyreke, IT, Thornton, or Fredette for not fighting through the screen. But if a screen is set properly, and the other team knows how to use a screen properly, the screen is going to work. So at that point, its on your big man to step out and push.
Long story short, we didn't defend the pick and roll very well. It caused our defense to breakdown, and more often than not, the other team scored.
