The Defensive Units That Will Decide the 2026 Season
Every championship season starts with a dominant defensive unit, and the 2026 preseason is stacked with position groups that have the talent to carry their teams to the College Football Playoff. Drawing from CBS Sports, Athlon, 247Sports and Pro Football Focus preseason evaluations, here is a position-by-position breakdown of the best defensive lines, secondaries and linebacker corps in the country.
Top 5 Defensive Lines
1. Ohio State Buckeyes — The Buckeyes return four starters from a defensive line that ranked second nationally in sacks (48) and tackles for loss (104) in 2025. Defensive end Caden Curry (10.5 sacks) and tackle Ty Hamilton (6 sacks) anchor a unit that has elite depth, with five-star freshman Eddrick Houston already rotating in. The interior push is the best in the country, and the edge rotation is deep enough to keep fresh rushers on the field for all four quarters. Ohio State's defensive line is the single biggest reason the Buckeyes are the preseason No. 1.
2. Georgia Bulldogs — Georgia reloads rather than rebuilds under Kirby Smart. Tackle Nazir Stackhouse returns for a fifth season, and edge rusher Damon Wilson II (9 sacks in 2025) is poised for a breakout junior campaign. The Bulldogs' defensive line room has produced five first-round NFL picks in the last three drafts, and the 2026 group is potentially the deepest yet.
3. Oregon Ducks — The addition of transfer edge rusher Nikhai Hill-Green gives Oregon one of the most disruptive pass-rushing tandems in the country alongside Jordan Burch. The interior is anchored by defensive tackle A'Mauri Washington, who has shed 15 pounds to improve his quickness for Dan Lanning's aggressive scheme.
4. Clemson Tigers — Clemson's defensive line tradition continues under new coordinator Mike Reed. End T.J. Parker (8 sacks) and tackle Peter Woods (5 sacks) return, and the Tigers have recruited the position better than any non-SEC program over the past three cycles.
5. LSU Tigers — Linebacker-turned-edge Harold Perkins Jr. moves full-time to defensive end in Blake Baker's scheme, and the addition of transfer tackle Gabriel Brownlow-Dindy from Texas A&M gives LSU a disruptive interior presence. The Tigers' front seven is the strength of the defense and the reason they are a dark-horse playoff pick.
Top 5 Secondaries
1. Notre Dame Fighting Irish — Cornerback Leonard Moore (97 overall, 4 interceptions, 11 pass breakups in 2025) is the best defensive back in the country, and safety Adon Shuler (93 tackles, 3 interceptions) gives the Irish the best safety-corner combo in the nation. New defensive coordinator Chris Ash inherits a secondary that allowed just 184.2 passing yards per game in 2025.
2. Ohio State Buckeyes — Cornerbacks Denzel Burke and Davison Igbinosun both return for their senior seasons, and safety Caleb Downs (89 tackles, 2 interceptions) is the best safety in the Big Ten. The Buckeyes allowed the fewest passing touchdowns in the conference last season and return all four starters.
3. Alabama Crimson Tide — Safety Malachi Moore returns for his sixth season, and cornerback Domani Jackson is entering his third year as a starter. The Tide's secondary has been the backbone of the defense through the transition, and Kalen DeBoer's hire of a defensive-minded coordinator has already paid dividends in recruiting.
4. Texas Longhorns — Safety Michael Taaffe (6 interceptions) and cornerback Malik Muhammad give Texas one of the most experienced secondaries in the SEC. The Longhorns led the conference in interceptions (17) in 2025 and return six of their top eight defensive backs.
5. Penn State Nittany Lions — Cornerback A.J. Harris and safety Kevin Winston Jr. anchor a secondary that has been quietly the best in the Big Ten East outside of Ohio State. Penn State allowed just 198.7 passing yards per game in 2025 and returns all three starting defensive backs.
Top 5 Linebacker Corps
1. Georgia Bulldogs — Linebacker Smael Mondon Jr. returns for his fifth season, and sophomore CJ Allen (89 tackles, 8 tackles for loss) is the reigning SEC Defensive Freshman of the Year. Georgia's linebackers are the deepest in the country, with four players who have started at least five games.
2. Alabama Crimson Tide — Deontae Lawson returns for his sixth season, and the addition of Ohio State transfer linebacker Damon Ervin gives the Tide a veteran presence in the middle. Alabama's linebackers are the key to the transition under new defensive coordinator Kane Wommack.
3. Oregon Ducks — Jeffrey Bassa (94 tackles, 3.5 sacks) is the Pac-12's best returning linebacker, and the addition of transfer Jestin Jacobs from Iowa gives Oregon a physical presence against the run. Dan Lanning's linebacker-friendly scheme continues to produce NFL-ready prospects.
4. Clemson Tigers — Barrett Carter returns for his senior season, and Wade Woodaz is one of the most underrated linebackers in the ACC. Clemson's linebacker corps is the strength of a defense that is replacing three starters on the back end.
5. Michigan Wolverines — Ernest Hausmann (87 tackles) and Jaydon Hood return for a Michigan defense that is transitioning to Kyle Whittingham's scheme. The Wolverines' linebacker room is experienced and deep, even if the scheme change takes time to implement.
How These Rankings Translate to CFB 27
In College Football 27, these position groups translate directly to gameplay advantages. Ohio State's defensive line (four players with 90+ power and finesse move ratings) is the toughest unit to run against in the game. Notre Dame's secondary, anchored by Leonard Moore's 97 overall, is the best pass defense in the game. Georgia's linebackers have the coverage ratings to match up with running backs and tight ends, making them the most versatile linebacker corps in Dynasty mode. If you are building a team in Dynasty, targeting players from these position groups — especially in the transfer portal — is the fastest way to construct an elite defense.
