Replay is f***ing dumb, if it comes down to pixels and shit the game should be called by ROBOTSHATE HATE HATE. I hate coach's challenges in sports. Getting things right shouldn't be a game within a game. Teams shouldn't be penalized for trying to get something right. It's just f***ed up and makes no sense.
There are replay officials. Let them watch the damn game and review everything and if something needs "further review" then they do a review.
None of it matters as as NHL officiating is as random as a chimp throwing shit at the wall.
I like that goalies get to warm up if entering the game after the other is injured.
