1) Because it’s sportsnet and they’re going to focus on a Canadian teamWhy phrase it this way? Avs are first team to score 5 goals or more in the first 5 games of an opening round series.
2) Because other teams have scored 5+ goals their first 5+ games before (not many like 4 of them IIRC), it just appears this is the first time that’s happened all against one team so they’re trying to avoid a bunch of dumb twitter people going at them when they read it wrong if they use the ‘first round series’ qualifier
