Fred Warner and Brock Purdy
Fred Warner is undoubtedly the leader of the 49ers defense. One could argue he serves as the defense's equivalent of quarterback Brock Purdy. Both Warner and Purdy receive plays and effectively lead their respective units. They demonstrate toughness, exhibit an instinct for the game, and possess high intelligence. Many would argue that their intelligence and feelings for the game truly set them apart from their peers. Interestingly, both Fred Warner and Brock Purdy were undervalued by scouts before being selected by the 49ers. Warner was considered a "good backup with the potential to become a starter." If that's not a significant oversight, I don't know what is. Fred Warner is arguably the best linebacker in football, and it's probably unnecessary to mention how undervalued Brock Purdy was, given his draft position and the ongoing doubt he faces from fans and the media.
Dre Greenlaw and George Kittle
If Fred Warner is the Brock Purdy of the defense, then Dre Greenlaw serves as the George Kittle of the defense. The parallels between them are striking. Dre Greenlaw was graded as a backup leading up to his draft, with his profile suggesting he lacked the ideal size to compete at the NFL level and relied on arm tackles. Similarly, George Kittle was also graded as a backup who lacked ideal size and sometimes struggled to gain separation and block effectively in the run game. Size is often considered crucial in the NFL, which makes it a common point of discussion among scouts. However, there's a clear disconnect between their potential and the scouts' ability to recognize it. Fortunately, the 49ers' scouts and coaching staff did see their potential. When healthy, Dre Greenlaw is one of the best tacklers in the NFL, while George Kittle is a run-blocking powerhouse and an elite pass-catching tight end.
Love for the game
Physical and draft profile parallels aside, there is a more important reason I liken Dre Greenlaw to George Kittle- their shared passion for the game. No one would seriously question either player's dedication. They both play with intense fervor, often making fans believe they could run through a literal brick wall. Sometimes, Greenlaw's passion can manifest as a bit too much enthusiasm, if that's even possible.
Putting parallels aside, I am incredibly excited for the return of such a significant portion of the heart of the defense, and I'm sure the 49ers feel the same way.
