I think reviews serve a certain purpose in the game. I do think they can take too long sometimes but with the two minute penalty if you challenge and are wrong, I think that is ok. I would like to see reviews on goals to make sure the puck crosses the goal line. Goals are very important and a VAR or American football goal line type camera could be very valuable. These are the types of calls I would like to see become automatic. I would also like to see any shot to the head to be reviewed. For all the other calls, I’m fine with them being reviewable as long as the coaches challenge it AND if they lose, they are penalized. I’m a bit in the middle about penalties being challengeable. I do think it could be valuable as it could be game deciding but also I don’t want to see coaches challenging every single game like you see in football. Hockey would be better off tightening up their rules and calling them as they are actually written first.
