The Detroit Lions are heading into the 2026 NFL season with serious postseason expectations. After building one of the league’s most competitive rosters, Detroit is aiming to return to the playoffs and make a deep run.

However, the team’s success won’t rely only on established stars such as quarterback Jared Goff, defensive end Aidan Hutchinson, and wide receiver Amon-Ra St. Brown.

For the Lions to reach their full potential, several young players entering their second NFL season must also take meaningful steps forward. Development from these players could play a major role in strengthening Detroit’s depth and overall roster performance.

Here are three second-year Lions players who need to elevate their game in 2026.

Tyleik Williams Must Anchor the Interior Defensive Line

Defensive tackle Tyleik Williams, the No. 28 overall pick in the 2025 NFL Draft, saw significant playing time during his rookie season.

Williams started 10 games in 2025 and finished with:

18 total tackles

2 tackles for loss

1 sack

3 quarterback hits

4 passes defended

Early in the season, he started the first six games alongside veteran defensive tackle DJ Reader. However, his role changed once Alim McNeill returned from a torn ACL injury, pushing Williams into more of a rotational role on the interior defensive line.

While Williams experienced typical rookie growing pains and finished with a 62.6 overall grade from Pro Football Focus, he also flashed his potential as a run-stopping defender. One of his most notable performances came in Week 18 when he recorded a tackle for loss and a pass defended in Detroit’s win over the Chicago Bears, coached by Ben Johnson.

Now that Reader has departed in free agency to join the New York Giants, Williams is expected to take on a much bigger role in the middle of Detroit’s defensive line. If he can develop into a reliable interior presence, it would significantly strengthen the Lions’ defense heading into the 2026 season.

Dan Jackson Needs to Prove He Belongs on the Roster

Safety Dan Jackson, the No. 230 overall selection in the 2025 NFL Draft, never had the opportunity to showcase his abilities during his rookie year.

Jackson suffered a leg injury during training camp and was placed on injured reserve, causing him to miss the entire season.

Before the injury, he was widely considered the favorite to secure Detroit’s fourth safety spot on the depth chart. However, the Lions added more depth at the position during the offseason by bringing in players like Christian Izien and Chuck Clark.

Because of this increased competition, Jackson will likely need to deliver an impressive performance during training camp to earn a place on the Lions’ 53-man roster for the 2026 season.

Dominic Lovett Must Fight for a Receiver Spot

Wide receiver Dominic Lovett, another seventh-round pick (No. 244 overall) from the 2025 draft class, appeared in 12 games during his rookie campaign.

However, his offensive role was extremely limited. Lovett played just 14 offensive snaps and did not record a single reception.

Most of his playing time came on special teams, where he logged 50 snaps. His most notable moment came during Detroit’s Week 6 loss to the Kansas City Chiefs, when he returned a kickoff for 22 yards.

Lovett now faces strong competition for a backup wide receiver role. Players such as Tom Kennedy, rookie Kendrick Law, and fellow second-year receiver Jackson Meeks will also be battling for roster spots during training camp.

To secure his place on the team, Lovett will likely need a strong showing in camp and preseason games.

Young Lions Could Be Key to Detroit’s 2026 Success

The Lions already have a strong core of veteran talent, but continued growth from young players will be essential if Detroit hopes to contend for a championship.

If Williams becomes a reliable defensive tackle, Jackson proves his value in the secondary, and Lovett contributes as a depth receiver and special teams player, the Lions could significantly strengthen their roster heading into the 2026 NFL season.
