"We can get a real sense of where [the referees are] leaning," King said. "If I feel they're off track a little bit, because two days earlier we had a very similar play and they were looking too hard, I'll say, 'Guys, you know what? We had a play like this the other day, and this is what the guys thought on this play.'
"And then they'll say, 'OK, you know what? You're right. I think the better call here is to keep our call,' or, 'We didn't see that live, and the better call is to overturn our call.' Now, I can't say, 'Listen, you guys are wrong, change your call,' because that's not the way it's written. They have the final call."
If the rule change is approved, hockey ops will have the final call. The department might use it for, say, 3 percent of reviews.
"I hope not," King said.
Ideally, it will be even less.
