Technique wasn't perfect, but I think you have to give Zach Randolph the pin on this maneuver on Blake Griffin.
The hand to the throat here is what will be the question. Did Randolph move his hand up to choke Griffin? Or was he holding him in place to keep him down, which is not good, but not a choke? That could determine if Randolph faces a suspension. Griffin does pull him down here, but it's always the second guy that winds up in trouble.
Grizzlies-Clippers has been called tightly, and they have still been fighting down and dirty.
