Hockey Prompt.

Well, personally, speaking from my own experience about these things, I feel like the idea of implementing video review is generally pretty useful as long as the coordination presented by the officials is good enough to the point where one has not to have to worry about whether it was the right call or not. I feel like it puts the onus on the referee to behave correctly, which while somewhat more of a pressure on the referee himself does help with the product itself since the arguability of a call no longer mars you. The time taken might be a handful but I think it's more beneficial for the game in the long run. The sole reason I wouldn't say we should do away with referees is that I don't believe machines are quite capable enough to do the task of refereeing a sport on their own, there are too many factors that a machine has yet to be fully trained on. I do think that it'll be a thing in the long run but probably not while we're still alive.
