NFL Defensive Rookie of the Year Odds: David Bailey and Rueben Bain Jr. Lead a Loaded Class

Two pass rushers are setting the pace in the race for NFL Defensive Rookie of the Year, and after watching camp reports roll in from Florham Park and Tampa, it’s easy to see why. Jets edge rusher David Bailey and Buccaneers OLB Rueben Bain Jr. have opened as co-favorites at sportsbooks, and the betting markets say this year’s defensive rookie class might be the deepest in recent memory.

Why the Market Loves These Two Pass Rushers

David Bailey went No. 2 overall to the Jets out of Texas Tech, and the tape backs up the draft slot. He led the entire FBS last season with 14.5 sacks and a 21.3% pressure rate, and he’s carried that motor straight into training camp. In a padless practice on July 30, Bailey logged three would-be sacks and repeatedly beat first-round left tackle Armand Membou, drawing praise from head coach Aaron Glenn for his get-off and hand strength. Sportsbooks have him at roughly +500 to win the award, with some boards as tight as +450.

Rueben Bain Jr. isn’t far behind at +500. The Buccaneers took the former Miami Hurricane 15th overall after he piled up 9.5 sacks in his final college season, and Tampa Bay retooled its defensive front around him this offseason, adding veterans like A’Shawn Robinson and Al-Quadin Muhammad to take pressure off the rookie early. Bain has stood out in every offseason session so far, from OTAs through the start of camp, flashing the speed-to-power bull rush that made him a top-15 pick.

Top Contenders

Behind the two edge rushers, the board gets crowded fast. New York Giants linebacker Arvell Reese sits around +700, landing in a defense that should get him on the field early as an off-ball linebacker with pass-rush upside. Washington’s Sonny Styles, a linebacker who reportedly wants the green-dot defensive-signal-caller role as a rookie, is priced around +850 — the kind of responsibility that tends to translate into tackle numbers and award votes.

Dallas Cowboys safety Caleb Downs, the No. 11 overall pick out of Ohio State, is also hovering around +850. Scouts consider him the most pro-ready defender in this entire draft class regardless of position, which matters for a rookie trying to win an award that rewards immediate, every-down production. Kansas City’s Mansoor Delane, a cornerback taken in the top ten, rounds out the group with odds in the +850 to +1000 range. Chargers edge rusher Akheem Mesidor is the next tier down, priced closer to +1700-2000, alongside names like Dillon Thieneman and CJ Allen further down the board.

David Bailey led the entire FBS in sacks last season — and he’s already out-rushing a first-round left tackle in camp before the pads have even gone on.

History says respect the volatility here. Last year’s winner, Browns linebacker Carson Schwesinger, opened the 2025 season at +6000 — buried outside the top ten in the odds — before rocketing to a dominant favorite by Week 17. The year before that, it was Rams edge rusher Jared Verse taking home the trophy. Defensive Rookie of the Year has a habit of rewarding players who get on the field early and stack production quietly rather than the preseason hype leader, so nothing about the current board is locked in.

That said, draft slot still matters. Top-half first-rounders get the reps, the play-calling trust, and the scheme fit that lead to counting stats. Bailey and Bain both check every box: premium pick, clear role, and a defensive coordinator already building the scheme around them. It’s a small margin separating the two, and betting insight from BetMGM shows the public spreading its money fairly evenly across the top names rather than piling onto one clear-cut choice — the kind of tight futures betting market that rewards research over gut instinct.

What Camp Reports Are Actually Telling Us

Padless practices always flatter pass rushers — no run blocking, no live tackling, reduced offensive-line intensity. Jets coaches have flagged that caveat themselves, and the same logic applies league-wide right now. Bailey’s snap count is also being ramped deliberately, climbing from 24 reps in week one toward a full workload by August. The real signal starts once the pads come on and the preseason games begin.

Bain’s situation carries a similar wait-and-see quality, but the raw traits are undeniable — the physicality and closing speed that made him one of the most disruptive interior-to-edge tweeners in this class showed up immediately in every offseason session the Buccaneers have run him through.

The Best Bet

David Bailey’s combination of draft capital, elite college production, and an immediate every-down role in Aaron Glenn’s defense makes him the safer lean at the top of the board, even in a virtual coin-flip with Bain. For value, Sonny Styles at +850 stands out — a linebacker being trusted with the green dot as a rookie tends to rack up tackles and stay on the field in obvious money-down packages, exactly the profile past winners have shared.

• Pick: David Bailey (Jets) +500
• Value alternative: Sonny Styles (Commanders) +850

Circle back once padded practices and preseason games start — that’s when this race actually starts separating contenders from camp hype.
