Okay well this take is fair. I've even conceded he may have suffered incidental contact to the head. But in the case of Backes' safety, it's pretty apparent the arm and shoulder are the initial point of contact so that's where the majority of the impact went, hence why he's uninjured and was present for practice today. But as to the dirtiness and suspendability of the hit, unless it's clear that the intent was to hit the head, it isn't "easily suspendable".
To be frank, I couldn't give a **** if Ritchie got suspended or not. The Ducks wouldn't be that much worse off without him. But through the three angles I've seen, all three indicate to me that the primary point of contact is the arms, then travels up to shoulders, and what is unclear is if the follow through traveled up to the head. The overhead view of the play is as unreliable as it is on any other play. Could he have clipped the head a little? Maybe, but at that angle it's just as likely that the shoulder appears to be behind Backes' head through the hit. The other angles are even less convincing as to whether or not the shoulder came into contact with his head. But in any event I don't think Ritchie intended contact to the head in any fashion. Should he have pulled up after Backes fumbled the puck? That's questionable and my answer would so long as we hold that standard to every player that finishes a check on a defenseman that cleared the puck. These kinds of hits on players that dispose of the puck happen all the time. The difference here was Backes was caught staring at his own flubbed pass.
EDIT: Despite your new, more fair stance on the matter though. My bitterness is derived from how you used every excuse you could to exculpate Brown from hitting a guy who couldn't see him, who didn't have the puck, and was in a vulnerable position. If we were to apply the same justifications you gave to Brown there isn't a shot in hell that you could say what Ritchie did was "easily suspendable." At best you would've at least given him some benefit of the doubt from the onset.
