Sidney Crosby's concussion has re-ignited the debate at the Board of Governors meeting at All-Star Weekend about whether the NHL is doing enough to prevent hits to the head. The NHL did adopt a new rule this season, Rule 48, which bans blindside hits to the head. "The blindside hit rule has made a difference in the way the game has been played," Blues president John Davidson said after the board meeting. "There's lots of hitting, only it's more intelligent. We're not trying to catch a guy with his head down, sideways, and knock a guy to the moon." It's clear from the discussion Saturday that owners want their general managers to further discuss the issue and whether the league should take the next step. "And so they should discuss it," Davidson said.
