I think Fraser's take is right on - this is just like Gryba's hit. Most people see it as clean, but the league's view is that if you go for a hard open ice hit then it is your responsibility to avoid head contact by making sure you can line it up perfectly. That does take some of the hitting out of the game, but given the severity of the concussion problem, I can understand it.
Gryba had no history, unlike Torres, and got 2. I'm guessing Torres get considerably more than 2. I suspect they'll respect that he has cleaned up his game after his massive suspension, but also want to send a firm message that he needs to stay away from borderline plays. My gut says 6 games - enough to ensure he isn't seen again in the LA series, but short enough that he will be back in the next series should the Sharks advance.
However, I'm confused on one point. With the new CBA, if it is 6 or more he can appeal. Given that many people see it as a clean hit, I'm guessing he would. What happens then? Can they get the appeal done in a day? If not, does he get to keep playing while the appeal happens? Maybe he'd just stay suspended for the 5 they can give him without appeal and the hearing would only be about the ones after that?
I suspect the NHL would hate to have a legal battle in the middle of the playoffs, especially if they think they could lose big ( like the appeal ruling there should not have been any suspension but the Sharks are already eliminated by then). That might mean they just keep it to 5 to avoid the issue.
