Except your completely ignoring Carlyle's rational for doing so. Carlyle believed putting Kessel and that line out would actually defuse the situation BECAUSE an enforcer protects his guys and fights other enforcers. He does not go after a purely skill player like Kessel who he knows isn't gonna try and fight him. The part where everything went nuts was because Scott is exactly that much of a douche bag to do so.
And yea, time left was around the 10 minute mark by the way.
