The bolded should 100% be correct. My guess is it will have no bearing on the result. The NHL effectively condones what Garland did. It is at the heart of their game management to suppress the effectiveness of the league's best players in the name of parity. I honestly know of no other sport that allows this sort of thing. All the other sports try to protect and highlight their stars sometimes, as in the case of the NBA, to the extreme.
In the NBA stars almost always get the benefit of the calls. If you did to say Lebron what players regularly do to McDavid, guys would be fouling out left and right and Lebron would kill them at the foul line.
Rather I suspect that what Garland admitting he did does is makes the situation worse. It will inspire others to do exactly the same and we know that in most instances it will go uncalled.
Not every team approaches McDavid the way the Canucks do. There are a few teams, like the Canucks--the Kings too--whose strategy is often to do whatever they can to stop McDavid and essentially dare the refs to call the game by the book. The Canucks know the refs probably aren't going to call absolutely everything, and the calls they do make are worth the trade off. Sometimes it backfires, like against the Kings last year when the refs weren't having any of it, which is why the Kings were so mad at the refs during that playoff series, because they knew that was really their only workable strategy.
Anyways, the refs from last night are incompetent. The sequence between McDavid and Garland really began at the start of the game, when the Canucks held RNH and then tripped Nurse during their powerplay, which directly led to the goal. The rules of the game were set, and the Canucks knew they were going to get away with all manner of obstruction. They committed uncalled infractions all night.
It is the only way they can beat the Oilers, but if the refs are incompetents, it's a highly effective strategy. It is
the only reason they won last night.
EDIT to add one more thing: I will never forget what Kerry Fraser said to Jason Gregor on his show a few years ago. He said, he always wanted the players to understand that the game was going to be called on
his (i.e., Kerry Fraser's) terms. That said everything anyone needs to know about NHL reffing. Never mind the rule book; the refs themselves are the source of the rules. That's how they view themselves. And I wonder how narcissistic one has to be to think that way.
