The Sports College of Canada and Fitness Institute has described Robert Marvin Hull as the "perfect muscular mesomorph." Hull stands 5 feet 10 inches and weighs 195 pounds. His biceps measures 15½ inches—bigger than that of either Cassius Clay or Floyd Patterson. His skating speed has been timed at 29.2 mph, the fastest in the NHL.
Perhaps the most fascinating statistic about Hull reveals that his wrist shot is faster than his slap shot. The slap shot is hockey's flashiest weapon and the one which brings the roars from the crowds. In launching one, the player stops the puck, brings his stick back in the same fashion a golfer uses when hitting a three-iron, then slaps the puck with all his might toward the net. At 95 mph Hull's slap shot is the fastest in the league, but his wrist shot, that seemingly easy flick he uses when in full flight, has been timed at 105 mph. Glenn Hall, one of Chicago's two alternating goalies, was asked recently how he feels during the hours of practice when he has to defend against Hull's attacks. "There are days," says Hall, "when you just step aside and leave the door wide open. It is a simple matter of self-preservation."
