Chiefs Preseason Opener Put A Few Roster Battles Into Focus

Despite resting key players, the Chiefs' preseason opener highlighted emerging talent and potential strategic shifts in their loss against the Rams.

The Chiefs’ preseason opener didn’t offer much in the way of stars, but it did give a few young players a chance to flash against the Rams in a 20-12 loss Saturday.

Patrick Mahomes never took the field. Matthew Stafford sat, too, along with several other starters for both teams. So the night belonged to the backups, the rookies and the guys trying to force their way into the conversation.

And a few of them did exactly that.

Chiefs rookie edge R Mason Thomas made his presence felt almost immediately. On the Rams’ second drive, he drove the tackle backward into the pocket and forced Stetson Bennett into a hurried throw that Jaden Hicks nearly picked off in the end zone.

Thomas wasn’t done there, either. He also got a hand on Ty Simpson’s arm to spoil a Hail Mary attempt before halftime.

That kind of instant pressure is exactly what Kansas City has been missing. The Chiefs ranked 17th in overall pressure percentage in 2025 even while blitzing at the third-highest rate in the league.

They need more disruption that arrives before the quarterback can react, and that’s part of why they drafted Peter Woods and Thomas. Woods has already stood out in camp, and Thomas backed it up in his preseason debut.

There was also plenty to like from Cyrus Allen, whose early buzz is starting to feel less like camp chatter and more like something real. He finished with two catches for 20 yards, including one tough grab where he had to leave his feet to secure a bad throw. He also hauled in a screen and showed some burst after the catch, though that play was wiped out by holding, one of many flags that kept breaking up the game.

His most encouraging moment didn’t even show up in the box score. From the 20-yard line, Allen ran a short route, then spotted space to the right and broke toward the sideline.

If Garrett Nussmeier had put a little more air under the ball, Allen looked like he had a touchdown waiting for him. That’s the kind of play that gets coaches’ attention: not just the hands, but the awareness.

Jaden Hicks also made a strong case for more snaps. Starting in place of the injured Chamarri Conner, he played into the third quarter, finished with a team-high seven tackles and nearly came away with that interception off Thomas’ pressure. Emmett Johnson helped himself, too, turning 12 carries into 59 yards and looking like a back worth a longer look, even though his best moments were erased by penalties - including a touchdown run wiped out by holding and another catch-and-run that didn’t count.

The Chiefs clearly wanted to get Jalen Royals involved, and he delivered in tight space when targeted. On the other side of the ledger, the offensive line depth had a rough night and was repeatedly flagged for holding as Kansas City piled up more than a dozen penalties.

At quarterback, the setup was exactly what you’d expect for a preseason opener. Mahomes dressed, warmed up and handled captain duties for the coin toss, then watched from the sideline.

Justin Fields got the start and, even though the Chiefs didn’t score on either of his drives, he threw the ball better than he has in camp. Saturday was probably his sharpest passing performance since arriving in Kansas City, and getting him with the first unit clearly helped.

Garrett Nussmeier followed and showed both sides of the rookie experience. He was uneven, as a seventh-round quarterback usually is, but there were signs. He also uncorked a gorgeous deep ball down the sideline that Jason Brownlee dropped.

Kansas City even dusted off a screen pass early, throwing one to Brashard Smith on the opening series for eight yards and a first down. It’s a call that has mostly vanished from the Chiefs’ offense, though there are reasons for that.

They haven’t had explosive backs to feature there, and defenses have often sat in deep shells that are built to take it away. If the revamped running back room can change the backfield equation, that wrinkle may have a chance to come back into play.

Chiefs Could Find Tight End Help In One Overlooked Rams Battle

The Chiefs preseason matchup with the Rams comes with a little extra relevance for Kansas Citys tight end room, even beyond the usual August evaluation. Los Angeles has built a crowded group there, mixing veterans with recent draft picks, and that depth has created a tough path for Davis Allen to carve out a steady role. For Kansas City, it is the kind of situation worth watching closely, especially with the Chiefs still looking for ways to strengthen their own blocking at tight end.

Allen has flashed the kind of sturdiness that keeps a player in the conversation, even if the opportunities to do much as a receiver have been limited by who else is ahead of him. If the Rams continue sorting out their tight end pecking order, Kansas City could get a useful look at a player whose value may travel better in the run game than in the passing game. And in a preseason setting, those little roster ripples can be enough to put an overlooked name on the Chiefs radar. [Read more 🡒]

Chiefs Were On The Wrong End Of A Rams QB Statement

The Chiefs spent much of their preseason meeting with the Rams chasing a quarterback they had not seen in an NFL game before, and Ty Simpson made the most of the spotlight. In his first action at this level, Simpson looked poised and efficient, completing 21 of 25 passes for 190 yards while helping Los Angeles to a 20-12 win and accounting for a major share of the Rams offense.

For Kansas City, it was less about the final score than the way Simpson handled the moment. He looked comfortable directing the attack and gave the Rams something to think about as they sort through their quarterback depth chart, which is exactly the kind of development that can linger beyond August. The Chiefs were on the wrong end of the statement, and now the Rams have a new performance to weigh as decisions get harder. [Read more 🡒]
