How Lions DC Kelvin Sheppard Should Be Similar to Aaron Glenn

The Detroit Lions have made significant strides on defense under the leadership of former defensive coordinator Aaron Glenn. Now, as the Lions move forward with Kelvin Sheppard taking over the role of defensive coordinator, there’s a clear blueprint of success to follow. Sheppard has a unique opportunity to build on Glenn’s legacy and elevate the team’s defense even further. Here’s why Sheppard should model himself after Glenn and how he can do so.

A Legacy of Aggressive Defense: The Aaron Glenn Influence

Aaron Glenn transformed the Lions’ defense with a focus on aggressive, ball-hawking plays and creating turnovers. Under Glenn’s leadership, the Lions defense became a formidable force, excelling in pass coverage and run defense alike. He emphasized the importance of cornerbacks as key contributors to the team’s success, not only in coverage but also in tackling and overall physicality.

For Sheppard, following Glenn’s aggressive defensive philosophy will be crucial. The Lions’ defense thrives when it’s able to force opposing offenses into mistakes, and Glenn’s emphasis on playing smart, physical football was a cornerstone of that success. Sheppard should prioritize maintaining that same level of intensity while adapting the defense to meet the evolving challenges of the NFL.

Emphasizing Versatility in the Secondary

One of Glenn’s most notable successes was his ability to develop a versatile secondary, with cornerbacks who weren’t just coverage specialists but were also tough, physical tacklers. This versatility helped the Lions’ defense succeed in both pass and run defense, ensuring they could handle any situation thrown at them.

Sheppard should continue to emphasize versatility in his secondary. Just like Glenn, Sheppard will need cornerbacks who can excel at coverage but also step up to tackle when necessary. Players like D.J. Reed, who excel in both facets of the game, are exactly the type of talent Sheppard should look to develop and empower.

Building a Defensive Identity Based on Physicality and Grit

Under Glenn, the Lions defense was known for its physicality. The cornerbacks didn’t just wait for passes to come to them—they went after the ball, often bringing down receivers with aggressive tackles. This kind of grit was infectious, spreading throughout the defense and creating an atmosphere where every player gave their all on every snap.

For Sheppard, creating that same physical mindset will be key. The Lions’ defense should be known for hitting hard and playing with relentless energy. Sheppard’s defense must be feared for its ability to disrupt plays and break up passes, just as Glenn’s defense was. This mentality should be instilled in every player, from the defensive line to the secondary.

Strengthening the Linebackers and Defensive Line

While Glenn’s work with the secondary was crucial, Sheppard’s focus will likely need to shift toward strengthening the linebackers and defensive line. The NFL is increasingly built around dynamic offenses, and an effective pass rush is just as important as strong coverage. Sheppard will need to ensure his linebackers can handle both coverage and run-stopping duties while developing a pass rush that can pressure opposing quarterbacks.

Building on the foundation laid by Glenn, Sheppard should continue to create a cohesive unit where the defense works together seamlessly. Whether it’s through blitz packages, effective linebacker play, or improving the defensive line’s pressure on quarterbacks, Sheppard’s defense needs to be versatile and unpredictable.

Mentorship and Player Development

Aaron Glenn was known for his ability to develop talent, particularly in the secondary. Players like Jeff Okudah, Amani Oruwariye, and others flourished under his tutelage, and Glenn’s ability to guide players through their development was a key factor in the Lions’ defensive resurgence.

Sheppard should follow in Glenn’s footsteps by prioritizing mentorship and player development. Creating an environment where players feel supported and encouraged to improve their skills is crucial. Just like Glenn did with his defensive backs, Sheppard should invest in developing young players, helping them reach their full potential and, in turn, elevate the entire defense.

Conclusion: Building on Success

As Kelvin Sheppard steps into the role of defensive coordinator for the Detroit Lions, he has a strong legacy to build upon. Aaron Glenn’s aggressive, versatile, and physical defense has set a high standard, and Sheppard has the opportunity to continue that work while adapting to the modern NFL landscape. By emphasizing versatility, physicality, player development, and a strong defensive identity, Sheppard can help the Lions take their defense to new heights, making it one of the most feared units in the league once again.
