I think video review is good for the game of hockey, but the implementation of it needs some adjusting for it to be fully embraced by players and fans. Video reviews often take far too long in the NHL, and that shouldn't be the case. Either the call on ice was clearly a mistake and it will be an easy fix to overturn it, or it is unclear and the call on the ice should stand. Refs should not need to spend five minutes looking at several slow mo replays to determine if a play was offside or not. The video will be either be quite explicit or not. Watching the same replay over and over doesn't get you a new view of the puck. Furthermore, why are the refs responsible for reviewing the replays when all they have is a small Ipad. Surely, the nhl operations centre has a much better setup for reviewing video.
