2026 IDP Rookie Sleepers: Undervalued Defensive Prospects to Stash in Dynasty Leagues
Jon Macri goes over some deep rookie targets, late-round values, and eventual breakout defenders who could be worth a stash in dynasty leagues.
The best IDP managers stay ahead of the market. Before preseason buzz reshapes rankings and ADP, the rookie draft season is the time to identify those defenders with startable IDP production potential hiding beneath the surface.
Every year, a select few under-the-radar rookies emerge as worthy dynasty stashes, and this list will look at those Day 3 NFL Draft prospects worth targeting near the end of dynasty rookie drafts.

LB Kyle Louis, Miami Dolphins
NFL Draft Capital: Round 4, 138th overall
IDP Rookie Ranking: LB8
The 2025 Miami Dolphins produced two top-12 IDP linebackers in Jordyn Brooks (LB1) and Tyrel Dodson (LB10). However, this roster was nearly completely overhauled this past offseason, where the team was torn down to the studs — with Brooks and Dodson still in place, at least for now. The Dolphins’ current 2026 depth chart doesn’t necessarily appear enticing for a fourth-round rookie to step into an IDP-relevant role, but as is the case with many on this list, patience in these low-cost fliers could pay dividends down the road.
The Dolphins added Jacob Rodriguez in the second round, along with Kyle Louis in the fourth, which, at the very least, should signal confirmation that Brooks and Dodson aren’t long for this team once their contracts expire at the end of the 2026 season. With Rodriguez a clear-cut benefactor of the team’s expiring contracts, Louis may be in for a similar trajectory if he’s able to translate to the next level, as his college prospect profile would suggest.
Louis comes out of Pitt as one of the more versatile linebackers in this class, with above-average usage on the edge and in the slot on top of his full-time linebacker role, and he thrived in all of those deployments. Louis earned strong career PFF grades across the board, resulting in a 92nd-percentile score in the linebacker prospect model, which puts him amongst a strong hit-rate bucket for future IDP success. Assuming the Dolphins remain in a rebuild, they’ll be looking to address other positions of value with more star power, but linebacker should logically remain safe from added competition right now, considering the investment during this past draft. Rodriguez and Louis leading the way at the position in Miami is well within the realm of possibilities starting in 2027, which has Louis locked on my IDP radar during this rookie draft season.
LB Bryce Boettcher, Indianapolis Colts
NFL Draft Capital: Round 4, 135th overall
IDP Rookie Ranking: LB12
Bryce Boettcher shares a similar outlook to the previously mentioned Kyle Louis, who was also taken in the fourth round by a defense that also invested a second-round pick at the position. The difference with the Indianapolis Colts defense compared to Miami is that there are no clear starters at linebacker on this roster, which puts second-round pick CJ Allen on a clear path to snaps, with Boettcher not far behind.
Akeem Davis-Gaither is currently a clear favorite to start the year next to Allen, given his experience in Lou Anaroumo’s defense, though he’s not so established that Boettcher couldn’t force his way into a larger role over time and with strong play. That strong play is where a flier on Boettcher could pay off, as his time at Oregon resulted in 80th-percentile PFF grades overall and 82nd-percentile coverage grades, while also performing well as a run defender.
The bet on Boettcher’s IDP value hitting doesn’t have to happen in Year 1, either, as he is a stash-able dynasty prospect that could deliver beyond this season, with Davis-Gaither only on a one-year deal himself. Boettcher’s strong college play translating to the next level could make Davis-Gaither more easily expendable at the end of his contract, opening up a spot for this high-end tackler to step into a starting role in 2027, if not sooner. IDP managers don’t necessarily need to spend rookie draft capital to acquire Boettcher outside of deeper leagues, but he is worth a taxi squad stash for rosters with room.
LB Kaleb Elarms-Orr, Buffalo Bills
NFL Draft Capital: Round 4, 126th overall
IDP Rookie Ranking: LB9
Kaleb Elarms-Orr delivered a breakout season this past year at TCU, earning a top-20 PFF grade for his position in the FBS both overall (84.4) and in run defense (89.1). On top of not being a liability in coverage, Elarms-Orr was among the most efficient prospects at his position during his career, which naturally is going to entice IDP managers who believe in that tackle rate translating to the NFL, even if it is a flimsy correlation at best.
The real sleeper potential with Elarms-Orr comes from a good landing spot on a defense with a new coaching staff that has no real investment in the current personnel, specifically, Dorian Williams, who is the projected LB2 at the moment. Williams has struggled through the first three years of his NFL career, often proving to be a liability in coverage and never really gaining any traction as a starter, outside of short-lived stretches as an injury fill-in.
With Jim Leonhard taking over as defensive coordinator and spending an early Day 3 pick on Elarms-Orr, he should be expected to get a fair shake to unseat Williams for that LB2 spot next to Terrel Bernard. It’s possible that Elarms-Orr’s IDP potential could hit as soon as this coming season, though helping matters is that Williams’ contract is up at the end of 2026. Elarms-Orr is well worth a stash in non-shallow dynasty formats, and has a real shot to contribute as soon as this season if he continues his strong play from this past season at TCU.
ED Dani Dennis-Sutton, Green Bay Packers
NFL Draft Capital: Round 4, 120th overall
IDP Rookie Ranking: ED12
Fourth-round success for EDGE rushers doesn’t come easily, but it isn’t an impossible path, with high-end examples like Maxx Crosby and Josh Sweat standing out as two of the more recent comparative sleepers. Of course, there are plenty of examples of those that never amounted to true IDP relevancy, too, though we’ll obviously hope that Dani Dennis-Sutton can beat the odds, and he has the landing spot and potential to do so.
The Green Bay Packers are thin off the edge, with Micah Parsons being the clear and lone established starter at this point, and even he is coming off a season-ending ACL injury. Lukas Van Ness is the penciled-in starter as a former first-round pick, though he hasn’t been overly effective at any point in his three-year career thus far. As a result, Van Ness has struggled to crack the top of the rotation at the position, and if that continues into Year 4, Dennis-Sutton could be the next logical next man up.
Dennis-Sutton has played a significant role at Penn State over the last three years, logging over 800 pass-rush snaps and racking up over 125 total pressures and 22 sacks. Dennis-Sutton’s pass-rush metrics also come in above average for the position, backed up by similarly solid run defense metrics, suggesting he has the ability to play an every-down role at the next level. Helping matters is that he is also an elite athlete, scoring a 9.96 Relative Athletic Score (RAS), adding to the optimism that he’ll overcome his draft capital, as the previously mentioned fourth-round successes Crosby and Sweat also measured as elite athletes coming out of college. For big-play and balanced scoring formats, Dennis-Sutton is the Day 3 EDGE target for me during this IDP rookie draft season.
S Michael Taaffe, Miami Dolphins
NFL Draft Capital: Round 5, 158th overall
The Dolphins make the list one more time, this time at the safety position, which is certainly one of the team’s thinnest positions, unlike at linebacker. Dante Trader Jr. and Lonnie Johnson Jr. were the expected starters for the team heading into the NFL Draft, though Johnson hasn’t exceeded 350 defensive snaps in a season since 2021, and Trader is just entering Year 2 of his NFL career.
Even if those two remain the Week 1 starters, it wouldn’t be a surprise to see a short leash given to both, as the lack of encouraging PFF grades for both players suggests that these aren’t starting-caliber options for the long-term. It’s still too early in Trader’s career to write him off, and for that reason, he might get a longer leash to show what he can do, but for the 30-year-old Johnson, Taaffe may be real competition for that starting spot.
Taaffe owns one of the best career coverage grades in this rookie safety class as a true deep safety prospect, having spent 65% of his career defensive snaps at Texas from a deep alignment. Despite that alignment, Taaffe was still able to be an effective tackler, earning a 10.2% tackle rate (73rd percentile) for his career, giving at least some hope that he’ll be able to overcome a similar deployment at the next level. Most of all, opportunity is king for Taaffe on a thin depth chart, and deeper IDP dynasty leagues could be looking at a roster stash at the position with a relatively short path to snaps in 2026.
