Best competition: IOL starters
The retirement off All-Pro center Frank Ragnow was a bit of a surprise but the team knew it was a possibility following the conclusion of the 2024 season. Now the Lions look to replace two starters along the interior of their offensive line heading into 2025.
Glasgow is the lone returning starter inside. He was playing right guard and center in OTAs. He had arguably his best season in 2023 at right guard before making the switch to left guard to accommodate Zeitler coming over in free agency and playing right guard last season. Glasgow had a bit of a down year by his standards last season, but hopefully moving over to his more natural right guard spot gets him back to playing the brand of football we saw from him in 2023.
Mahogany was working at left guard with the first-team offense in OTAs. He played well when given an opportunity as a rookie last year and that looks like his initial landing spot to start camp.
At center, the team mostly had the rookie second-round pick Ratledge there in the spring. The Lions like his versatility and skillset.
Heading into camp, it seems like it will be Ratledge, Glasgow and Mahogany inside to start, but head coach Dan Campbell and run game coordinator and offensive line coach Hank Fraley are looking for good competition to push them.
Colon, Awosika, Muti, Niese and Sorsdal are veteran players with plenty of experience under their belt. Frazier was drafted in the fifth round and the coaches will give him plenty of opportunity to make a mark. He played a ton of really good football at LSU. Don't sleep on Eguakun, either. The team liked his development on the practice squad last year and he'll be looking for a role inside.
Twentyman's take: It's a little unusual to enter training camp with so many questions along the offensive line. We're used to maybe one spot up for grabs, like last year at left guard, but not three.
The offensive line has been such a strength for this team the last few years, but competition isn't necessarily a bad thing, and getting a little younger upfront along the interior means the Lions could actually be a little more athletic. How quickly the new players can fit in with veterans Sewell and Decker on the edges is going to impact how good of a start this offense can get off to in 2025.
Sewell, already considered one of the best tackles in football, said his goal this offseason was to gain strength without losing any athleticism. I am excited to see what that looks like once the pads come on.

By the numbers:
2: Sacks allowed in three seasons and 37 starts in the SEC at Georgia over the last three seasons for Ratledge.
3rd: Sewell became just the third tackle in Lions history to earn multiple First-Team All-Pro selections.
5: Teams that have recorded at least 6,500 yards and 70 touchdowns in a season. Detroit (2024), Kansas City (2018), Denver (2013), New England (2007) and Miami (1984).
13.7: The Lions had the second-lowest three-and-out percentage in the NFL last year. Only Atlanta (9.9) was lower.
33: Sacks allowed by Detroit's offense in 2024. That ranked in the Top 10 in the NFL.
50: Collegiate starts for Frazier at Florida International and LSU. Frazier played a total of 3,283 offensive snaps during his college career with 2,509 coming at LSU.
90.5: Sewell's Pro Football Focus run-blocking grade last season, the second highest among all NFL tackles last season.
Quotable: "Competition brings out the best of a unit," Fraley said this offseason. "It will weed out the weak, too, the guys that just can't keep up. Talking with all our guys this year, there's a lot of opportunity to compete.
"It's just, 'OK, I'm coming in and working hard and do what I can do and take care of what I can take care of.' It's only normally going to make you a better player. It's going to make those other guys around you better. We're going to breed competition, and I think you're going to see the best from all these young men moving forward."
