Niskanen swung two fisted baseball bat style at Sid.
No, he didn't.
Ovi basically did that with the hit to the back of Sid's helmet/neck.
Niskanen brought his arms ( and stick) up in front to his chest in what looked to me like a move based out of self-protection as much as anythjng originally.
Even in slow motion, that's what I see.
Now, in the photo in the USA Today, it clearly shows Niskanen's stick hitting Crosby's jaw hinge, right between Niskanen's hands. That's a solid knock-out blow very likely to cause a concussion every time.
I know more than a bit about concussions. I've had a couple myself and my son was in the UPMC Concussion Profile for several years.
The question remains is whether Niskanen's blow was intentional. Unlike Ovi's hit or the one at the Winter Classic which nearly knocked Sid out of hockey, intent is not so clear on the Niskanen hit. Both players were sliding to the ice. Sid might already have been concussed by Ovi's blow.
But, the photo REALLY looks bad. If the photo was the only evidence, I'd have to suspend Niskanen for 6 months.
As it is, I'm not sure. If it were players named Smith snd Jones snd playing for random teams, I'd probably call the Niskaern hit accidental. Given it's the Capitals, down 0-2 and hitting Crosby, it certainly would raise questions in ANY reputable league.
But, this is the NHL. As long as hits like these are part of the game, it's not a major league, but UFC with skates.
