The biggest roster questions facing the Kansas City Chiefs heading into the 2025 NFL season are focused on the offensive line. Specifically, analysts and fans want to know how the left side will fare after a full spring of retooling at both tackle and guard.

The early reports from Chiefs head coach Andy Reid continue to be positive. Reid spoke to the media on Thursday, with offseason training activities winding down, and gave updates on both presumed new starters up front.

The Chiefs drafted Josh Simmons in the first round of the 2025 NFL Draft out of Ohio State as a high-ceiling tackle coming off of major injury. The team also signed Jaylon Moore to compete for the left tackle role, giving them two new options at a position at which four players rotated as starters one year ago.

Andy Reid gave positive updates on Josh Simmons and Kingsley Suamataia as the (presumed) new starters get to work.

At left guard, the Chiefs jettisoned All-Pro Joe Thuney in a trade with the Chicago Bears in a move that moved money elsewhere, allowing the team to retain right guard Trey Smith on the franchise tag. In Thuney’s place along the left side of the interior, the Chiefs are shifting Kingsley Suamataia, their second-round pick in 2024, inside with the hopes he can thrive there.

Both Simmons and Suamataia bring significant upside to both positions, but the proof will be in the pudding, as they say, once the season begins. That said, early returns are strong and Reid provided greater detail as to how both are doing.

Reporters asked Reid about Suamataia’s improvements inside and what has allowed him to look better at guard than at tackle one year ago.

“First of all, [Suamataia’s] got experience. And then, he looks more comfortable there. He seems to be picking it up pretty well. Not that we’re going full speed contact, but he has an opportunity to go against Chris [Jones] and that’ll surely help him for the season,” said Reid.

Reid also addressed the learning curve for Suamataia after coming in and earning the starting left tackle role only to lose it after two weeks of the regular season.

“It looked like he learned as he went,” said Reid. “It was rough, obviously, early, and expectations were high. You come into a championship-caliber team and get thrown in there at left tackle. It’s not always the easiest thing for a young guy, but I think it was a great experience and I think that will tell itself out as he goes forward.”

As for Simmons, Reid says he’s progressing well in his recovery from a torn patellar tendon last fall and he’s been able to take on more at OTAs.

“You know what, [Simmons] is doing a nice job. We weren’t sure quite how much we were going to get out of him, but he looks strong. He’s been jumping in and taking the team reps now, which he was just doing the individual stuff before. You can definitely see the talent. He’s gotta keep learning the stuff that Andy’s [Heck, offensive line coach] teaching him, fundamentally and technique-wise, but he sure has a good attitude about it,” said Reid.

The Chiefs will get an even better look at both players and how the left side of the line might shape up when mandatory minicamp begins on June 17.
