Which Lions player has the most to prove in 2026?

As a team, the Detroit Lions have a ton to prove this season.

After taking a step back in 2025 for the first time in the Dan Campbell era, doubt is starting to creep in both within Detroit and from the national audience. It hasn’t been a splashy offseason, and with some drama surrounding the departures of Alex Anzalone, Taylor Decker, and Terrion Arnold, the vibes have certainly been off.

Proving the doubters wrong starts at an individual level, and there are plenty of Lions players who must use this season to turn their career around or show that they belong in Detroit.

So today’s Question of the Day is:

Which Lions player has the most to prove in 2026?

My answer: On offense, one name jumps to the top of the list for me: Christian Mahogany.

After his rookie season, it looked like the Lions may have found a gem in Mahogany. While he only played a handful of games, the fifth-round pick finished the season on a high note, projecting to be the team’s left guard of the future. Unfortunately, 2025 was filled with injuries and subpar play. Mahogany will have to compete with Ben Bartch and Miles Frazier just to win back his starting job, but the bar should be higher than that. He needs to prove he can be a potential high-end starter again, because the bar is very high when it comes to offensive line expectations in Detroit.

On defense, the list is much longer, but I think the most pressure is on Derrick Barnes. With Anzalone now gone, Barnes will be expected to not only be a full-time starter, but take on multiple roles. He needs to take his pass rush, coverage skills, and even edge setting to a new level and justify the three-year, $24 million extension he was given. If he succeeds, the Lions defense has a chance to bounce back in 2026. If he fails, it seems unlikely Barnes will reach the final year on his contract, which includes a hefty $6.145 million option bonus.
