The Chiefs played without Patrick Mahomes.

They played without Travis Kelce, Chris Jones, Nick Bolton and Trent McDuffie. They played without many highlights either.

The Seahawks blistered the Chiefs in the second of three preseason tilts 33-16 at Lumen Field in Seattle. Here are five observations from immediately after the game:

1. That run defense. Oof. I say this not because of one exhibition quarter but rather because it was already a pertinent question: Can we really assume the Chiefs run defense will repeat last year’s success?

It was a failure Friday.

To be fair, the Chiefs played without the man they paid a lot of money to stop the run, middle linebacker Nick Bolton. He was one of several players offered a rest.

But they played without much resistance in that department, either. The Seahawks’ backfield combined for 11 carries for 114 yards and a touchdown in the first quarter alone.

They rushed for nearly 300 yards in the game. The Chiefs finished seventh in the NFL in yards per rush allowed last season, but it’s notable that was an anomaly compared to the previous six years, when they averaged 25th in the league and never finished better than 15th.

The formula still produced a couple of Super Bowls in that time frame, but the pass defense had better be stout.

Here’s what won’t help that: Nazeeh Johnson, Mike Edwards and Nohl Williams were among a half-dozen players shaken up during the game. 2. Kingsley Suamataia. Oof again.

Kingsley Suamataia finished his first pass-protection snap on his backside. His finished his last one staring backward at his quarterback.

It was a rough night, and he didn’t exactly perform well in his first preseason showing.

This is where the preseason reps matter most. The individual battles, the one-on-ones along the offensive line specifically, offer prime evaluation.

Josh Simmons, at left tackle, is earning a lot of attention this preseason camp. Kingsley Suamataia will be the one drawing the opponents’ attention once the regular season commences. His move from left tackle to left guard remains an evident work in progress.

3. That other tight end It’s confounding that tight end Robert Tonyan finished last season on a practice squad.

He’s been about the most sure-handed player in camp this month, but his pair of second-quarter catches demonstrated a couple of other useful features. After catching a short pass, he put his head down and used his size to turn it into a first down. Five plays later, he used his experience for a touchdown.

With the Chiefs on the 1-yard line, quarterback Gardner Minshew rolled right, and all the coverage rolled with him. Tonyan noticed it and simply halted his route, letting the coverage cross over his face. He found the opening, and Minshew found him for a 1-yard score. Tonyan, or “Big Bob” as Travis Kelce affectionally calls him, is squarely on the 53-man roster. He led the Chiefs on Friday with five catches for 41 yards and the touchdown.

4. The RB rotation The individual performances are what we can see.

The rotations are a result of what the Chiefs have already seen. They’re telling, in other words, and here was a telling feature: Carson Steele got some run with the first-string offense in the opening quarter. He played in front of Elijah Mitchell, who is slipping into a precarious position ahead of cutdown day in 11 days. Mitchell later entered the game in the second quarter.

Steele finished with seven carries for 22 yards. Mitchell carried four times for 9 yards.

Steele said he spent the offseason working to become a better fullback, but that was his own doing, not at the Chiefs’ request. It’s not materialized much in training camp.

But he might have an edge to make the roster at running back just the same.

5. The highlight Skyy Moore. A loooong exhale.

Moore returned an 88-yard punt down his own sideline for a late fourth-quarter touchdown, and I’m not sure there’s a player who needed something, anything, to go well more than he did. He dropped not one but two open passes earlier in the game.

A former second-round pick, Moore has spent all of training camp on the outside of the 53-man roster bubble.

The outing Friday seemed destined to seal his fate — and then he made a play. He’s still on the outside looking in, but it had to feel every bit relief as much as excitement.

At this point, it’s no longer about his physical ability. It’s in his head. And that’s when it might be best for a change of scenery.
