Underdog Dynasty ranks top FCS defenders for 2026 season

The first thing that jumps out is the shape of the board: it is linebacker-heavy, but the names behind it are scattered enough to matter for the title race. Dayton, Marist and the Ivy League put multiple impact defenders in the conversation, while Wagner and Jackson State keep the map national and remind you that FCS defensive talent still comes from every corner of the subdivision. That is why preseason defender rankings matter, and why they sit in the same lane as the Buck Buchanan Award, the FCS’s annual honor for the subdivision’s most outstanding defensive player, won in 2025 by Mercer edge rusher Andrew Zock. NCAA.com had the 2025 finalists out on December 2, 2025, which is the kind of benchmark these summer boards are really trying to anticipate. HERO Sports’ preseason coverage uses the same logic, treating the offseason as the time to identify the returning standouts who can shape September and October.

1. Mirko Jaksic, University of Dayton

Jaksic lands at No. 20 for a reason that goes beyond reputation. The redshirt sophomore defensive tackle started all 11 games in 2025, made 33 tackles, added 6.5 tackles for loss, and finished with two sacks and one quarterback hurry, production that helped Dayton go 7-4 overall and 5-3 in the Pioneer Football League. First Team All-PFL is the cleanest shorthand for what he already was: a front-line player who earned his place with real snaps, real disruption and a full season of work.

2. James Kratochvil, Marist University

Kratochvil gives Marist a seat at the table and helps explain why the Pioneer League shows up more than once on this board. When one league can put both Dayton and Marist into the discussion, it says something about how much front-seven value is still being developed outside the usual playoff bluebloods. His honorable-mention placement fits the larger picture here, where the best defenders are not simply high-volume tacklers but players who can tilt the structure of a game.

3. Braylon Howard, Cornell University

Howard is part of the Ivy League push that makes this ranking more than a scattered list of names. Cornell joining the board alongside Harvard means the Ivy is no longer just supplying intrigue on offense or in schedule talk, it is producing defenders worth tracking nationally before the season even kicks off. That matters in a year when the line between strong regular seasons and playoff relevance is thin, because one league showing multiple defenders of this caliber usually points to deeper program health.

4. Sean Line, Harvard University

Line completes the Ivy League pair and gives Harvard another signpost in a conference that has crossed from curiosity to real FCS relevance. Two Ivy names in the same defender pool tells you the conference has enough talent to shape games on both sides of the ball, and that defensive depth is now part of its identity. In a playoff field where every possession gets magnified, that sort of balance can become a seed line advantage later on.

5. Ethan Appolon, Wagner College

Appolon keeps the Northeast Conference in the mix and prevents the list from collapsing into a few familiar geographic hubs. Wagner’s presence shows the board is wide, not just deep, and that is what makes preseason rankings useful to anyone trying to understand where the next set of breakout defenses could come from. A defender from Wagner on the same list as Ivy and Pioneer names is a reminder that FCS talent distribution is still one of the subdivision’s most interesting truths.

6. Kam Sallis, Jackson State University

Sallis gives Jackson State and the SWAC a place in the conversation, which broadens the board even further and keeps it from feeling like a private-club exercise. With the ranking described as linebacker-heavy, his inclusion reinforces the idea that the best all-around defenders are still the ones who diagnose, run and finish plays, not just the ones who post the flashiest splash numbers. That is the kind of player who changes a third-and-5, then changes a playoff bracket later if the roster around him holds together long enough.
