The Public Has Picked Its Sides
Conference Championship Sunday arrives with the betting public lining up behind the favorites. In the AFC, 75% of spread bets are backing the New England Patriots as 4.5-point road favorites at Denver. In the NFC, nearly 79% of bettors are riding the Seattle Seahawks at -2.5 against the Los Angeles Rams.
That kind of one-sided action typically signals value on the other side. Both home underdogs have angles worth considering before kickoff.
Denver: Largest Home Underdog in Conference Championship History
The Broncos enter today as the biggest home underdog in a Conference Championship game since the 1970 AFL-NFL merger. The market’s logic is straightforward: Bo Nix fractured his ankle in overtime against Buffalo last week, and Jarrett Stidham takes over. Stidham has started four career games and thrown zero passes in either of the last two regular seasons.
The panic feels excessive. The line swung roughly 6.5 points after Nix went down, well beyond the 3.85-point average swing oddsmakers typically assign between starter and backup. Denver’s defense finished second in yards allowed and third in points allowed during the regular season. The Broncos forced five turnovers against the Bills, including two Josh Allen interceptions and three fumble recoveries.
There’s also history favoring Denver. The Broncos are 8-2 straight up and 9-1 against the spread in Conference Championship games. They’ve played host to this game six times at Mile High and lost just once, back in 2005 against Pittsburgh. That remains their only home Conference Championship defeat.
The Patriots counter with Drake Maye, who has looked excellent as a favorite this season. He went 12-0 straight up and 10-2 ATS when favored by three or more points, winning by an average of 16 points per game. But Maye has also struggled with ball security in the playoffs, fumbling the ball multiple times across two games while taking 10 sacks.
Denver’s offensive line allowed just 23 sacks this season, tied for the fewest in football with the Rams. Stidham should have time to operate, and fading 75% public action has historically produced value.
Los Angeles: Battle-Tested and Covering Concerns
The NFC Championship presents a different contrarian case. The Rams have played three straight road games and survived two down-to-the-wire finishes. They beat the Panthers 34-31 in the Wild Card round, then escaped Chicago 20-17 in overtime after Caleb Williams threw a desperation touchdown with 18 seconds left to force extra time.
Neither performance inspired confidence. Los Angeles failed to cover in both games as a road favorite. The Rams were -10 against Carolina and -4.5 against Chicago. That makes Matthew Stafford’s squad 0-2 ATS in these playoffs.
Yet the market keeps betting against them covering. Seattle draws 79% of the spread action and 73% of the money. The Seahawks have won eight straight and demolished San Francisco 41-6 in the Divisional Round. They’ve earned their favorite status.
The counterargument: these teams split their regular season series with each deciding game coming down to a field goal or less. The Rams won 21-19 in Week 11 at home. The Seahawks won 38-37 in overtime in Week 16 after trailing by 16 points in the fourth quarter. Combined margin: three points across two games.
Stafford has been valuable as a playoff underdog. He owns a 5-2 ATS record in postseason games where he’s getting points, and he’s 5-0 ATS when catching seven points or fewer. At +2.5, that trend holds.
The underdog has also covered in seven of the last eight Rams-Seahawks meetings. Seattle’s defense has been suffocating lately, allowing just 19 points across their last three games, but their Week 16 meltdown against this same Rams team raises questions about whether public confidence has outpaced the actual edge.
Historical Context Favors Underdogs Here
Conference Championship underdogs have struggled historically, going just 20-24 ATS since 2003. That makes this round the only playoff stage where underdogs fall below .500 against the spread.
However, teams with a rest advantage have gone 27-17 straight up in Conference Championship games since 2004. Both Denver and Seattle had extra recovery time compared to their opponents. The Broncos played Saturday while the Patriots played Sunday. The Seahawks essentially had two weeks of rest, enjoying a bye before demolishing the 49ers.
Home teams with rest advantage have been even more dominant at 21-7 straight up in that span.
The Numbers to Watch
Both games feature compelling contrarian setups, but the market is pricing them differently. The Broncos represent the more dramatic contrarian play. They’re catching the most points any home team has received in a Conference Championship since the merger, and the line has already moved a full point in their direction from the opening -5.5.
When 75% of bets push a line the other direction, sharp money is often at work. That movement suggests professional bettors see value on Denver despite Stidham’s inexperience.
The Rams offer a tighter spread in a rivalry game that has produced one-possession finishes all season. Los Angeles has failed to cover twice this postseason, but both games went to the final minute. Their playoff experience, with Stafford’s 2021 Super Bowl run, contrasts sharply with Sam Darnold’s first Conference Championship start for Seattle.
Public money floods favorites in the playoffs, especially against backup quarterbacks and in rivalry rematches. The contrarian case for both underdogs has merit, though variance in a two-game sample means neither is a guarantee. The data suggests the public’s certainty may be overstated.
