Since the rule changes following the lockout, the speed of the game in the NHL has increased significantly.Everybody who knows anything about physics knows that when something increases its speed, there is a bigger ending momentum and ultimately impact.
Rule 48 was implemented in that late stages of last season to try and curtail the head shots that were taking place. 48.1, titled, "Illegal Check to the Head" sets out that "A lateral or blind side hit to an opponent where the head is targeted and/or the principal point of contact is not permitted."
The topic of head shots in the NHL has come to the forefront especially after more and more NHL players have sustained concussions as a result from the head shots. Some of these players include Sidney Crosby (twice), David Booth, Marc Savard, and most recently Max Pacioretty.
One man who was involved in the fore-mentioned rule changes was current Senior V.P. and Director of Hockey Operations of the NHL, Colin Campbell. Campbell is currently the main disciplinarian in the NHL but has come under fire recently. This is because Campbell is directly responsible for suspending (or in some cases, not suspending) the player who delivers the head shot.
The following videos will show why Campbell no longer deserves his lengthy title in the NHL.
