Ottawa's #1 Defense vs. Toronto's Dead-Last 5-on-5 Numbers — The Stats Say This Isn't Close

Let's be upfront about the context first: this is a preseason split-squad game on September 23, which means neither team is dressing a full lineup, stars are likely sitting, and roster construction for this specific game is essentially unknown. Betting these games carries real risk that has nothing to do with the underlying team quality. With that caveat clearly stated, here is what the data actually shows.

Ottawa's defensive profile from last season is legitimately impressive. The Senators allowed just 2.7 high-danger chances against per game, which ranked #1 in the entire league. Their expected goals against sat at 2.7 per game, also #1. Their 5-on-5 possession metrics back this up — xGoals% at 56% (#2), Corsi% at 53% (#3), Fenwick% at 54% (#3). This is a team that controlled games structurally, not just by score.

Toronto's numbers from the same period are almost the mirror image, and not in a good way. Their xGoals% sat at 46% (#29), Corsi% at 45% (#31 — dead last), Fenwick% at 45% (#31 — dead last). Their xGoals Against per game was 3.48, ranking 31st. Their actual goals against per game was 3.6, also 31st. At 5-on-5, the Leafs were one of the weakest possession teams in the league by every available measure.

The one area where Toronto shows a hint of resilience is penalty kill, sitting at 85.5% (#12) versus Ottawa's 84.1% (#18). Ottawa's power play at 18.5% (#6) gives them a modest edge on special teams overall, but in a preseason split-squad environment, special teams deployment is often limited and unreliable anyway.

On the injury side, Ottawa is missing Artem Zub — a legitimate top-four defenseman who logged 120 blocks and 30 points last season — along with Jake Sanderson, Jordan Spence, and Warren Foegele. That is a significant chunk of their regular-season roster absent from Wednesday's lineup. Toronto is missing Dakota Joshua, a bottom-six piece, which is a much lighter blow.

Here is the honest bottom line: the regular-season statistical gap between these two teams at 5-on-5 is enormous and genuinely favors Ottawa. But no market signals are firing, no algorithmic line movement patterns have been detected, and no insider systems have been flagged for this game. There is zero market confirmation of an edge. And in a preseason split-squad game where Ottawa's top defensive players — the very reason their numbers are elite — are sitting out injured, projecting those regular-season numbers onto this specific lineup is a stretch.

If you are looking for a lean, the underlying team structure points toward Ottawa, and their home ice in a division rivalry adds mild value. But sharp bettors should recognize this for what it is: a thin angle in a preseason game with incomplete rosters and no signal confirmation. The stats tell a compelling story about two teams heading in opposite directions. Whether that story applies on September 23 is a much harder question to answer.
