There is blood in the water, on the topic of predatory hits on defenceless players, and those with I.Q.s larger than their shoe sizes are well aware that every time they make contact now with someone in a vulnerable position, they are apt to face the wrath of the NHL's supplemental discipline department.

No one wants to kill an opponent and risk being suspended for four games.

Which brings us to Anaheim centre Ryan Getzlaf's hit on Vancouver defenceman Dan Hamhuis during Wednesday night's 4-3 Ducks win at Rogers Arena.

In real time, it looked bad.

Hamhuis's head rattled off the glass from the impact, and he appeared to be out, or in and out of consciousness, as he lay on the ice. He was down a long time. Canucks coach Alain Vigneault could be seen remonstrating with the officials on the ice, the words "Come on now!" clearly readable from his lips.
