What is at stake
An interconference game, NFC against AFC. It counts in both overall records — which is what seeding is settled on first — and in neither team’s division or conference record.
What the ratings imply
The differential above is arithmetic on two published numbers:
The Gridiron King’s 2026 final efficiency ratings, plus
1.7 points of home field.
It is not a projection, a value, an edge or a lean, and nothing on this site
compares it with the betting line to tell you one is better. Until 2026
games are played it is last season’s measurement of two rosters that have
been through a draft and a free-agency window since.

Points / game
Points allowed / game
Opponent-adjusted ratings from The Gridiron King’s 2026 final numbers. Bars share a scale within each row, so the two lengths are comparable; the brighter side is the better of the two, and a longer bar is the better number — including the rows where a lower figure is the good one. Pace is the exception: it is how fast a team plays, not how well, so neither side is lit and a longer bar there means only more plays.
Team stats
The box-score store these rows are built from has not been produced for this league yet, so no preview carries points and yards for and against. The form, trend and series blocks below are built from this site’s own files and are not affected.

Lines are captured from ESPN's board before kickoff and locked at kickoff, so an in-play price cannot overwrite the number a game is graded against.

These are regular-season totals for
the season named on each card — the players who led that team that year,
taken from ESPN's team leaders. That list is keyed to the season, not to today's
roster, so a leader who has since signed elsewhere, been traded or retired still
appears against the year he earned it; the
roster
pages and the depth chart on each team page are where the current squad is.
A team switches to this season's numbers once it has played a game.
