Detroit Lions Defender Explains The Biggest Difference Between Aaron Glenn And Kelvin Sheppard
The Detroit Lions’ defense has been playing with a renewed sense of energy and passion this season, and much of the credit is being directed toward their new defensive coordinator, Kelvin Sheppard. While the scheme has roots in what former DC Aaron Glenn established, the difference in sideline demeanor and player connection is palpable. Cornerback Amik Robertson recently provided a fascinating look into this dynamic, explaining the key differences between the two coaches.
Detroit Lions: Robertson’s Take On Aaron Glenn Vs. Kelvin Sheppard
Appearing on “The St. Brown Brothers” podcast, Amik Robertson was asked by wide receiver Amon-Ra St. Brown to compare the coaching styles of the current and former defensive coordinators. Robertson’s answer was direct and revealing, pointing to two key areas where Sheppard stands out: passion and personal connection.
“I think Shep is a little more passionate,” Robertson explained. “He understands me a lot more and he puts high expectations on me.”
This comment speaks volumes.
“Sometimes we feel like our coach is our teammate,” he said. “But of course you know you got to respect him at a different level.”
This “player’s coach” mentality, combined with an intense passion for the game, seems to be the perfect formula for this young and hungry Lions defense. Sheppard’s ability to connect with his players on a personal level while still commanding respect has been instrumental in the unit’s success.
The Sheppard Effect: Run Through a Brick Wall
Anyone who has watched the Lions this season has seen Kelvin Sheppard’s infectious energy on the sideline. He coaches with a “run-through-a-brick-wall” intensity that his players clearly feed off of. After the defense’s dominant performance against the Tampa Bay Buccaneers on “Monday Night Football,” Sheppard was a major topic in national media, with many highlighting his sideline presence as a key motivator.
This visible passion is the most obvious difference between his style and that of Aaron Glenn. While Glenn was known for his calm and composed demeanor, Sheppard is an emotional and vocal leader. He is animated, constantly communicating with his players and celebrating their successes with genuine excitement. This energy creates an environment where players feel empowered and are motivated to match their coach’s intensity.
Robertson’s feeling that Sheppard “understands me a lot more” is crucial. It suggests that Sheppard is not just coaching a scheme; he is coaching individuals. He takes the time to understand what motivates each player and tailors his approach accordingly. By placing high expectations on a player like Robertson, Sheppard shows confidence in his abilities, which in turn inspires the player to elevate his game.
Building on a Foundation
It’s important to note that Sheppard’s success is not a complete departure from the past. Robertson acknowledged that it is clear Sheppard learned a great deal during his time as the linebackers coach under Aaron Glenn. The defensive scheme still carries many of Glenn’s principles, but Sheppard has added his own flavor and adjustments.
The transition from Glenn to Sheppard represents an evolution, not a revolution. The foundation was in place, but Sheppard’s unique leadership style has unlocked a new level of performance. He has taken a solid defensive framework and injected it with a potent dose of passion, energy, and personal connection. The results are evident on the field, where the Lions’ defense is playing faster, more aggressively, and with a noticeable swagger.
A Defense Forged in Fire
The difference between a good coach and a great one often comes down to the ability to connect with and inspire players. Amik Robertson’s comments provide a valuable window into why the Detroit defense is thriving. Kelvin Sheppard’s blend of youth, passion, and a deep understanding of his players has created a culture of accountability and high energy.
Cubs Linked to Cy Young World Series Standout as Free Agency Rumors Swirl
The 2025 MLB season is over for all but two of the league's 30 teams.
Therefore, while there's a lot of interest surrounding whether the Toronto Blue Jays can take down the Los Angeles Dodgers in this year's World Series, the fan bases of many teams are more interested in how their roster is going to improve this winter, hopefully so that they can be watching their team in the World Series this time next year.
The Chicago Cubs have many offseason decisions to make that will ultimately mold the franchise's chances of making a deep run in the 2026 postseason. Among these are whether to try and re-sign star outfielder Kyle Tucker (and how much they're willing to spend to bring him back) and which of their numerous free agent relievers they're going to pursue.
What's more, Chicago could be active in trying to bolster their starting rotation, as their current starting staff has several question marks. There are a couple of compelling free agent starting pitchers available in this year's free agency market. But the one that might be the best fit for the Cubs is still playing games
In an October 22 article, MLB.com insider Mark Feinsand listed the Cubs as one of three potential fits for Blue Jays pitcher Shane Bieber.
Bieber is a fascinating free agency target for Chicago. Just a few years ago, Bieber was one of the premier pitchers in the entire sport, which is proven by his being a two-time MLB All-Star, the 2020 AL Cy Young Award winner, and the recipient of a Triple Crown in 2020, which is when a pitcher leads the league in Wins, ERA, and Strikeouts.
The 31-year-old Bieber then suffered a torn UCL in his throwing elbow in April 2024, which kept him sidelined for over a year. The Cleveland Guardians traded him to the Blue Jays before the 2025 trade deadline (before Bieber made his return from injury). He made his 2025 season debut on August 22 and has been solid ever since, posting a 4-2 record and a 3.57 ERA in seven regular-season starts.
Bieber has been decent in three starts this postseason. However, a great World Series performance against the Dodgers would work wonders for his free agency stock and could convince the Cubs that he's worth a contract once he becomes available later this winter.
