Brown's "controversial" hit on Hudler in game 1 of the Detroit vs Anaheim series was legal and clean. It was shoulder to shoulder and Hudler got rid of the puck less than 2 seconds before. It didn't help Hudler that he wasn't paying attention, or was slightly bent over as he was turning up the ice. The problem is that Hudler was skating in one direction, but playing the puck in the opposite direction. Therefor his head is turned around watching his back pass before it almost gets taken off.
Shown in slow motion it looks bad, but in real time it's legit. The 3rd clip is a reverse angle on this you tube link, and it clearly shows Brown hitting Hudler shoulder to shoulder. Enjoy. Tonight is HNIC, can't wait to sit down with some scotch and enjoy the game.
