Obvious? No, actually it's a good non-call. Lunqvist lost his balance bracing for an impact that never came.
IMO the problem with the officiating is they no longer seem to be thinking about how the foul affected the flow of the game like they used to. (Did it take away a scoring chance? Did it cause a scoring chance?) It's basically, see a penalty call a penalty, which leads to this inconsistent scattershot officiating. Officiating used to be about game management, and it doesn't seem to be like that any more.
