As Florida State University (FSU) prepares for the 2026 football season, much attention is focused on sophomore defensive lineman Mandrell Desir. Recognized by CBS Sports as one of the top returning players in college football, Desir had an impressive freshman year, recording 30 tackles, 7.5 tackles for loss, and 6.5 sacks, earning him All-ACC Honorable Mention and the title of ACC Defensive Rookie of the Year runner-up. His performance has drawn national attention, yet it remains somewhat underappreciated. With the departure of Darrell Jackson Jr., FSU's defensive front faces new challenges, making the development of players like Desir even more critical. The team's defensive strategy, particularly in the 3-3-5 scheme under defensive coordinator Tony White, will be tested as opponents adapt to FSU's young pass rushers. The health of Deamonte Diggs and the continued growth of Kevin Wynn will also play significant roles in shaping the defensive lineup. Overall, how Florida State fills the void left by Jackson while maintaining pressure on opposing offenses will be a key storyline in the upcoming season.
