5. Video Replay.
Everyone hates it, get rid of it.
The coaches challenge is dumb too. I would rather the NHL get some calls wrong than to pause any game for ten minutes to debate the minutia of a parallax angle or whatever the heck they are talking about for 20 minutes when I hit mute.
And that's just goals, which I can at least understand. Video replays on offsides are an affront to the inventors of the game.
6. Arrogance.
The fans hate the electronic boards. Fair or not, they are universally hated. The NHL doesn't listen to its fans and this is just one example.
7. Ads on Jerseys and Helmets.
This is just disgusting greed and the cost isn't worth the reward. Like the electronic boards, the extra profits just aren't worth the degradation of the product. You can't put a price on the goodwill of your fans, and no matter what trends come and go, the only thing that will always be universally uncool is selling out.
