NHL - Discouraging Hitting in the Playoffs

Kronwall was suspended 1 game for the hit in the clip below. I do not understand how this hit warrants a suspension? In my opinion, it should not even have been penalized. Kronwall didn't leave his feet, his elbows were down, the puck was at Havlats feet...it doesn't make any sense.

One of the first things you are taught as a hockey player is to always skate with your head up. It was not Kronwall's fault that Havlat wasn't ready for the hit. Sure it was a dangerous hit, but hockey is a dangerous sport. Remember Scott Stevens playoff hits in the 1990's and early 2000's? Most of his hits were extremely dangerous but he wasn't suspended everytime he layed the boom on someone.

Honestly, the NHL needs the big hits and big fights, especially in the playoffs. The more hitting, the higher the TV ratings will be. If we ever want to see NHL hockey on ESPN again, the NHL cannot keep suspending players for incidents like this.
