Actually, Murray took a penalty in the 2nd OT, a pretty lame holding call. Kovalev has a rep for " embellishment ", and I think that, and Ribeiro's antics caused the Ref's to say " here we go again ", and ignore it. I saw the slash, wasn't worth a penalty in the regular season, let alone in double OT. I do think if the team and player involved were different it would have got a whistle. Historically, between the Bruins and Habs, this sort of thing has resulted in a major to the Bruins, and the Spanish Inquisition post game.
