Scott Burnside: First of all is there anyone who doesn't cringe watching Sidney Crosby glide up to Ryan O'Reilly from behind and swat him between the legs with his stick Tuesday night? Ouch. But let's have a little perspective here. Dirty? Yes. Worthy of a cautionary call from the department of player safety? Certainly. But worthy of a suspension? No. And not because he's Sidney Crosby but because the NHL has shown the threshold for supplemental discipline and specifically a suspension is much, much higher than the love tap administered by Crosby. Earlier this week Matthew Tkachuk of the Calgary Flames was suspended two games for a dangerous elbow to the head of the Los Angeles Kings' Drew Doughty.
