This is what proponents of video review in sports consistently get wrong. Yes you can look at that play last night, call it a good goal and be technically correct but it's still a bad goal that should not have counted and which, 9 times out of 10, gets whistled offside before the puck ever gets into the net.
Pro sports is, at the end of the day, not life and death. What it actually is, is an entertainment product. And for that product to work, the calls can't just be technically correct, they have to look and feel "right". That goal last night didn't look or feel legitimate and since perception is reality in such things then it's not a righteous goal no matter how you want to parse the rulebook. Fans don't want plays like this to cause a 10 minute delay in the action while a bunch of nerds replay the incident over and over trying to spot the fly shit in the pepper. The only people who need everything to be technically correct are gamblers. Fans just want the game played and officiated in a way that looks and feels right and which provides entertainment value. That's why refs don't call penalties on every shift despite the fact that they see clear fouls committed on every shift. To do so would destroy the flow of the game and render it an unwatchable mess.
And in the case of that goal last night, it's only a good goal if you give Makar the benefit of the doubt regarding his intent. Otherwise he was just shoveling the puck ahead of himself, unaware that his teammate was offside. Yes technically the puck wasn't touching his stick for a second, but Makar was never not in complete control of it. It was one fluid play on his part and it feels wrong when you look at it at normal speed. It should have been ruled offside to comply with the spirit of the rule rather than ruled onside to comply with the letter of the rule because it's better for your product in the long run. The last thing any fan wants or needs is to be told that something which clearly looked and felt wrong is actually right, followed by Ron McLean, the referees' most sycophantic apologist, spend the intermission lecturing the fans about why the refs made a "great call".
If it feels like a bunch of bullshit to the fans, then that's what it is, even if it technically isn't.
