I think Coach K is one of the best/worst (depending on how you look at it) at working the refs with intimidating stares and harsh words. The thought of ringing up Coach Williams (either one), K, and Knight because of a lack of bench decorum seems ludicrous. The ref that rings up one of those Coaches with the game on the line for a lack of bench decorum needs to be examined by a physician for elephantitus of the you know whats.
