The problem on Rays dunk was that Taj Gibson didn't do anything but stick like glue to Davis. When Korver got picked off by the screen Taj needed to sink at a better angle to protect the basket. Also whoever was guarding the ball let a pass go through the middle of the paint.
It wasn't all on Korver. That is what team defense is and Chicago basically got out coached with bad player positioning. Funny considering the coach used to coach for Boston.
