The NFL Scouting Combine has wrapped up, signaling the start of the next phase: top-30 visits for draft prospects. The Detroit Lions are set to host linebacker Chaz Chambliss from Georgia this week. Chambliss, who has a stellar collegiate career including two national championships, showcased his potential with notable stats in his final season, including 6.5 sacks and a solid pass rush grade. With defensive changes under new coordinator Kelvin Sheppard, the Lions are evaluating their linebacker depth, particularly with Derrick Barnes entering free agency.

The Chicago Bears have made significant moves to address their offensive line by acquiring All-Pro guard Joe Thuney from the Kansas City Chiefs, along with Jonah Jackson from the Detroit Lions. These transactions mark a decisive shift in strategy as General Manager Ryan Poles aims to bolster the Bears' protection schemes ahead of the 2025 NFL Draft.

With the 10th overall pick, many speculated the Bears would target top offensive linemen like Will Campbell or Kelvin Banks. However, after the addition of Thuney and Jackson, the need for a first-round interior lineman has diminished. This shift could allow Poles to explore other positions, potentially targeting an edge rusher or skill position player.

In the upcoming NFL offseason, the focus shifts to the impactful interior defensive linemen, who are poised to hit free agency. These players, while less celebrated than exterior pass rushers, play a critical role in both run defense and pressuring quarterbacks. Free agency is expected to see some significant moves, with players like Poona Ford and D.J. Jones looking for new homes. Ford's performance with the Buffalo Bills and Jones' solid season with the Denver Broncos highlight the depth of talent available.

In particular, players like B.J. Hill of the Cincinnati Bengals, who has been a key component of their defensive line, and Levi Onwuzurike from the Detroit Lions, ready to step into a full-time role, are intriguing options for teams in need. Milton Williams of the Philadelphia Eagles demonstrated his prowess in the Super Bowl and is also expected to attract interest. With contracts projected by Spotrac giving insight into market values, teams will be keen to secure these defensive assets to bolster their defenses.

NFL free agency is set to begin on March 12, bringing pivotal decisions for the Detroit Lions regarding their eight biggest free agents. Carlton Davis, coming off a solid season with two interceptions and a notable performance, is expected to attract significant interest, making his return uncertain. Meanwhile, offensive guard Kevin Zeitler's success with a high run-blocking grade suggests the Lions will prioritize his re-signing as he may face less competition on the market.

Levi Onwuzurike is likely to stay, as he emerged as a valuable asset in his third season. Conversely, linebacker Derrick Barnes, who has struggled to establish consistency, may benefit from a fresh start elsewhere. Ifeatu Melifonwu, who showed promise in the previous season, is anticipated to find a new home after battling injuries. Finally, Tim Patrick's reliable production suggests he will likely stay with Detroit, along with fan-favorite Dan Skipper. However, edge rusher Marcus Davenport is expected to depart after underwhelming performances.
