The AP has a good report on the NHL's efforts to crack down on hits to the head. In it, Sidney Crosby, whose battle with the aftereffects of a concussion have given the problem a very high-profile face, says the NHL should ban all hits to the head.
"We're not talking about a lot. The game's not going to change," he said, citing statistics that showed that only 50 of the 50,000 hits in hockey last year were to the head. "Whether it's accidental or not accidental, you've got to be responsible out there. At the end of the day, you can do a lot more good than what it's going to take away from the game."
This preseason, the NHL has been aggressive in suspending players who have delivered dangerous hits.
It's still unclear when Crosby will return. There have been positive signs for him in training camp, but he still hasn't been cleared for contact, and he'll need to spend some time getting ready even after he is cleared.
