You play by the rules and guidelines that are in front of you. Right now, in the regular season a a win is a win is a win and is worth 2 points. Doesn't matter if it's RW/OT/SO. The goal is to win the game. The team that has the most wins according to the rules should be viewed as the better team.
In the playoffs there's no 3 on 3 OT, but still... a win is a win. Doesn't matter if you win them all in OT or not.
I get using RW/OT/SO as tiebreakers but I still think overall wins should be higher than those on the list. You win more games you should get priority. I don't even think that should be debatable.
I don't like the 3 point system... in fact I don't like the point system. I would just make a win a win and a loss a loss. Use winning % instead of points but this is hockey and that's not going to change.
3v3 and shootouts are a gimmick so that fans can leave the game with some closure without putting the players through endless 5v5. You get points for being good at it, so it does have value. But everyone knows it’s a compromise which is why it doesn’t exist in the playoffs.
Under old rules, more of Vegas’s OT games would result in ties rather than wins, and Colorado would likely have already clinched. This is the smallest possible way to acknowledge that.
