I have problems with the officiating as well. There are parallels to be drawn for me to SB 52 where the way things were called all year (in that case catches, in this case head hunting) were for some reason called differently. That is a problem.
To me the NHL can't dip their toe in here; either all games including the playoffs, have no room for fighting and headshots, or none do. And if they are going to straddle this fence, Bettman is creating a situation he claims to not want. He wants a Speed and Skill game but then "rewards" clutch and grab, interferring, tripping, head hunting when it matters most. If I'm a GM of a team on the cusp next season, I am absolutely having a Thorty type player on my team. Someone who wont hurt me too much, but who will bust someone in the face when they take a run at one of the their teammates. Do you think Barbasol is taking runs at people the way he did if a Shawn Thorton is available to whoop his ass?
All that being said, I have accepted the entertainment aspects of American sports long ago. The reluctance to utilize technology and "more eyes" to get things right; in any of the sports, tells you all you need to know. "The Human Element", "Judgement Calls", "Tradition","it will slow the game down too much" are all cop outs. But fighting that is like pissing in the wind. The games are too fast to have one set of humans call it accurately. Football and Hockey specifically should have a full second set of officials in the booth watching every camera angle possible on every play. Not to call a hold here or a a trip away from the play there. They won't though because leaving it "traditional, like the way it was when Concrete Charlie played!" leaves them an out, it gives them plausible deniability if they want to "build the drama"; which is what advertisers insist on as they're the ones paying.
But the way the series was called has nothing to do with two lines barely showing up. Whether it was injury, fatigue, or just getting their **** stuffed in, the top two lines failed this team. Just like the defense did in SB 52. The refs didn't leave Jordan Richards out there trying to cover people he can't. The refs didn't cause the vast majority of the Bs best players to go -26.
