If there has been a defining aspect of the NHL playoffs so far, it has been that getting payback for tough or questionable hits and plays is as much a goal for teams as scoring. It's not that fights and extracurricular rough stuff are uncommon to playoff hockey — they definitely aren't — but there seems to be an eye-for-an-eye mentality that has taken hold. In other words, should Blackhawks goalie Corey Crawford be worried come Tuesday in Game 3 against the Phoenix Coyotes? Crawford's standout play somehow has gotten lost in the shuffle. Coyotes goalie Mike Smith, meanwhile, has been in plenty of headlines. Hawks rookie Andrew Shaw's head-to-mask collision with Smith in Game 2 has highlighted just how contentious the series has become.
