Seahawks at Chiefs: Preseason Finale Brings Roster Battles, Defensive Storylines to Arrowhead

It’s the final tune-up before the real games begin, and while the standings show a pair of 0-2 preseason records, the numbers tell a different story about how these two teams are built for the season ahead. The Chiefs have the talent edge on paper, and the betting market agrees—Kansas City sits as a 3-point home favorite with the total at 45.5. My model, which has been sharp on exhibition games, projects a 27-21 Chiefs win and likes KC to cover the number at a 62% confidence clip. Let’s dig into why.

Team Analysis: Defense Leads, Offense Lags

Kansas City Chiefs

The Chiefs haven’t scored much this preseason—13.5 points per game, ranking #24 out of 31—but the offense has been moving the ball better than the scoreboard suggests. They’re averaging 275 total yards per game, with 160.5 through the air and 114.5 on the ground. That’s a balanced attack, but the lack of touchdowns (zero per game in both pass and rush) is concerning. The offensive line has been decent, allowing just 2.0 sacks per game, and the return of Trey Smith to practice this week is a positive for that unit.

Defensively, the Chiefs have been the bright spot—allowing only 18.0 PPG (#16) with a strong showing on third down. The rookie defenders have flashed speed and athleticism, and that unit has kept KC in games even when the offense sputters. That said, safety depth is a real issue. Chamarri Conner is out with a knee injury, and Alohi Gilman was pulled before the Tampa Bay loss with a back issue confirmed by Andy Reid. That leaves the position group thin for this one, and it’s a vulnerability Seattle could exploit if their passing game gets going.

Seattle Seahawks

The defending Super Bowl champs have looked flat this preseason, managing just 11.5 PPG (#26) and 203.5 total yards per game (#30). The passing attack has been nonexistent—91.5 yards per game (#30) on only 23.0 attempts—while the run game has been respectable at 112.0 YPG (#14). They’re a run-first offense, but with only 23.5 carries per game, they’re not committing to the ground either. That conservative, low-volume approach has led to a slow pace (46.5 plays/game) and a turnover differential of -1.5 per game.

Seattle’s defense has also been mediocre, allowing 18.0 PPG (#17) but with no takeaways and no interceptions in two games. The secondary is banged up—rookie DB Bud Clark suffered a concerning injury early in the Tennessee loss—and the unit has taken a heavy injury toll across the preseason. That’s a big red flag against a Chiefs offense that, while not explosive yet, has the receivers to test a thin defensive backfield.

Key Matchups to Watch

Chiefs Offensive Line vs. Seahawks Defensive Front

With Trey Smith back, KC’s line should be more stable, but this is still a game where depth matters. Seattle’s defensive line hasn’t generated much pressure—zero sacks in preseason—so Mahomes (or more likely the backups) should have time to throw. The Chiefs’ pass protection has been solid, and that edge could decide the game if Seattle can’t get home on third down.

Seahawks Ground Game vs. Chiefs Front Seven

Seattle’s 112.0 rush YPG is the one area they’ve been serviceable, and they’ll lean on that against a Chiefs defense that’s been stout but hasn’t faced a heavy dose of run in their first two preseason games. If the Seahawks can control the clock and keep the game low-scoring, they can stay within the number. But their pace is so slow (46.5 plays/game) that they’ll need to be efficient with every possession—something they haven’t been, given 1.5 turnovers per game.

Backup Quarterback Battle

Both teams are likely to see their starters for a series or two, but the battle is really between the second- and third-string QBs. The Chiefs have gotten nothing from the position in terms of TDs, but they’ve protected the ball (0 INTs). Seattle’s signal-callers have been turnover-prone (1.5 TO/game). That disparity in ball security is a key factor—turnover margin has decided both of these teams’ losses this preseason.

The Model’s Pick: What the Numbers Say

My model is projecting a final score of 21-27 in favor of Kansas City, which means the Chiefs cover the -3 spread and win outright on the moneyline. The confidence sits at 62%, which is solid for a preseason game where starters are limited.

Why does the model like KC? It comes down to three things: offensive efficiency, defensive consistency, and pace. The Chiefs are averaging 275 YPG vs. Seattle’s 203.5—that’s a 71-yard gap per game. Even if you adjust for preseason usage, that differential matters. KC’s defense has been the more reliable unit (18.0 PPG allowed, but with a better third-down rate), while Seattle’s has been banged up and is missing key pieces.

The turnover margin also favors the Chiefs by 1.0 per game (-0.5 vs. -1.5). In a low-scoring game—the total is 45.5, and both offenses have struggled to reach 14 points—a single turnover could swing the cover. The model’s predicted total is 48 (21+27), which is slightly over the number, but I wouldn’t rush to the over. The projection is based on a moderate uptick in scoring from both offenses, but the pace disparity (59.5 plays vs. 46.5) suggests Seattle will slow this game down, and that could keep the total under unless KC scores in bursts.

Betting Angles and Line Movement

The spread has been stuck at -3 since it opened, and the total hasn’t budged off 45.5. That tells me the market is comfortable with this number, but it also means there’s no public lean to fade or follow. With no movement, the value comes from the model’s edge on KC -3. The Chiefs are a better team, playing at home, and they have a deeper roster—that’s why they’re the pick.

The total is a trickier spot. Both teams rank in the bottom third in scoring, and Seattle’s slow pace is a natural under factor. However, the Chiefs’ defense has been solid but not dominant, and they’ve allowed 18 PPG. If KC’s backups can put up a couple of scores, the total could go over, but I’d lean under if forced to pick—just not with confidence. The model doesn’t have a strong read on the total, so I’m passing on that.

Situational Factors: Preseason Finale, Roster Battles, and Injuries

This is the last chance for fringe players to make the roster, so expect heavy rotation. The Chiefs have wrapped up camp and are back in Kansas City, which should give them a familiarity edge. The Seahawks, meanwhile, are coming off a tough road loss and have their own roster questions.

Home field matters in preseason—coaches often play to the crowd, but more importantly, the travel and focus levels can differ. Seattle has to go on the road for this one, and after a 16-19 loss at Tennessee, they may be more concerned with staying healthy than winning. The Chiefs have a thinner safety group, but they’ve been practicing at home and should be more settled.

Injury-wise, the biggest names are out or limited. Conner and Gilman for KC are out, weakening the back end. Bud Clark for Seattle is a question mark—if he’s limited or out, that’s another blow to their secondary. Trey Smith’s return for KC is a positive, but it’s preseason, so don’t overvalue it.

The Verdict: Lean KC -3, But Don’t Bet the Farm

My model says it’s Kansas City -3 with 62% confidence—that’s a solid play, but not a slam dunk. The Chiefs have the statistical edge on both sides of the ball, and Seattle’s injury-depleted defense is a concern. The slow pace from the Seahawks could keep it close, but the Chiefs’ extra possessions and better efficiency should be enough to cover.

Final call: Seahawks vs. Chiefs: Take Kansas City -3 in the preseason finale. If the line moves to -3.5, I’d still lean their way, but -3 is the sweet spot. The total is a no-play for me—both offenses are a mess, and Seattle’s pace could throw off the board.

Remember, it’s preseason, so bet accordingly. But the numbers are the numbers, and they point to a Chiefs win and cover.
