The easiest NFL rooting advice is useless: root for your own team to win.
The interesting question is what should happen everywhere else.
FSN’s NFL Rooting Guide answers that by using the same 5,000 full-season simulations behind the Playoff Predictor. For each unplayed game, FSN compares the simulated seasons in which one side wins with the seasons in which the other side wins, then measures what changes for every other team.
That produces a very different Week 3 viewing map. A game can be relatively ordinary for the two teams on the field and enormous for someone watching from another division city.
After Thursday night’s Atlanta-Green Bay result was locked, these were five of the largest remaining division-odds swings on FSN’s Week 3 board.
1. Arizona at San Francisco: Seattle wants Arizona
Impact for Seattle: roughly 14.8 percentage points in division odds if Arizona wins.
This is the largest hidden division lever on the current board. Seattle is 2-0 after beating Arizona 31-7 in Week 2. San Francisco is also 2-0. The NFC West race therefore has an obvious early fault line: the two undefeated teams are already threatening to separate from the rest of the division.
Seattle cannot directly affect Sunday’s Arizona-San Francisco game. The next-best outcome is clear in the FSN simulation: an Arizona upset. That branch removes a win from the 49ers and increases Seattle’s probability of winning the NFC West by nearly 15 percentage points compared with the San Francisco-win branch.
That does not mean Arizona is likely to win. The Rooting Guide is not making a prediction here. It is measuring which result helps Seattle more.
2. Seattle at Washington: San Francisco wants Washington
Impact for San Francisco: roughly 11.5 points in division odds if Washington wins.
The mirror image appears in the same division. San Francisco fans have a major reason to care about Seattle’s trip to Washington.
FSN’s Week 3 confidence model likes Seattle heavily in the matchup, but the rooting model asks a different question: if the Commanders pull the upset, how much does San Francisco’s season path improve?
The answer is a lot. A Washington win cuts directly at Seattle’s clean start and shifts the NFC West race toward the 49ers. This is why FSN keeps the tools separate. The Game Simulator asks who is likely to win one matchup. The Rooting Guide asks which outcome helps a third team. Those are not the same problem.
3. Baltimore at Dallas: Cincinnati wants Dallas
Impact for Cincinnati: roughly 9.4 points in division odds if Dallas wins.
Cincinnati has started 2-0. Baltimore is 1-1 after a Week 2 loss to New Orleans. The Bengals therefore have an opportunity to gain ground without taking a snap in Dallas.
If the Cowboys beat Baltimore, FSN’s simulation gives Cincinnati a significantly better AFC North path than in the Ravens-win branch. The effect is especially notable because Cincinnati still has its own divisional game at Pittsburgh on Sunday. A Bengals win plus a Ravens loss is the classic two-result swing that can change a division quickly.
4. Los Angeles Rams at Denver: Kansas City wants the Rams
Impact for Kansas City: roughly 9.0 points in division odds if Los Angeles wins.
The Chiefs are 2-0, but the AFC West remains a multi-team race. Denver enters Week 3 at 1-1. A Broncos win over the Rams would keep Denver within immediate striking distance.
The rooting model therefore gives Kansas City a clear preference: Los Angeles.
This is a good example of why rooting interests are often counterintuitive. The Rams are not an AFC team, and a Kansas City fan might otherwise view the Sunday night game as unrelated. In the simulation, it is one of the Chiefs’ most important outside results because it directly changes the record of a division rival.
5. Los Angeles Chargers at Buffalo: New England wants the Chargers
Impact for New England: roughly 8.9 points in division odds if the Chargers win.
Buffalo is 2-0 and sits at the top of the AFC East. New England is 1-1 after beating Pittsburgh. The Patriots’ most valuable outside-game result is therefore straightforward even if the opponent comes from the AFC West: a Buffalo loss.
FSN’s conditional simulation branches show a Chargers win producing almost nine additional percentage points of AFC East title probability for New England compared with a Bills win.
That is a huge swing for a game New England does not play in. It also illustrates why division odds can move much more sharply than overall playoff odds. Buffalo losing helps New England specifically in the race for first place even if the Patriots’ wild-card path changes less.
Honorable mention: Carolina wants Las Vegas over New Orleans
Carolina’s biggest outside interest is also substantial. FSN shows the Panthers gaining roughly 8.7 points of division probability in the Raiders-win branch against New Orleans.
That makes sense after Week 2. Carolina crushed Atlanta, while New Orleans upset Baltimore. The NFC South is suddenly much more fluid than it looked after opening weekend, so one head-to-head result involving the Saints can reshape the Panthers’ path quickly.
Why this is different from a normal rooting article
Most rooting guides can be written from the standings: root against your division rivals, root against teams ahead of you in the wild-card race and root for conference tiebreak help.
FSN’s model tries to quantify the size of those preferences.
For every unplayed game, the season simulation compares the downstream outcomes in the home-win branch and the away-win branch. The guide gives playoff qualification the most weight for bubble teams, then increasingly values division and No. 1 seed leverage for teams whose postseason position is stronger.
Small differences are labeled small. A tenth of a point is not treated like destiny. That matters because Monte Carlo results naturally move slightly from run to run.
The Week 3 second-screen map
If you are a Seahawks fan, Arizona-San Francisco deserves almost as much scoreboard attention as Seattle-Washington. If you are a 49ers fan, reverse it. Bengals fans have a reason to keep Baltimore-Dallas on the second screen. Chiefs fans should care about Rams-Broncos. Patriots fans should care about Chargers-Bills.
That is the real value of the rooting model: it turns a 16-game slate into a personalized map of leverage.
FSN takeaway: the biggest game for your division race may be one your team is not playing. Week 3 already has several outside results worth roughly nine to 15 percentage points of division probability in FSN’s conditional simulations.
