With the NFL Draft in the books, it is officially dynasty rookie draft season. Some leagues that started slow drafts immediately after Mr. Irrelevant’s name was announced (Kobee Minor, for what it’s worth) may already be deep into the later rounds. By the time you’re in round five of a 12-team rookie draft, all of the obvious names are long gone. But whether you’re on the clock right now or just looking ahead, it’s good to know some deep sleepers for rookie drafts. Here are a few of our favorite dynasty rookie draft deep sleepers.

Dynasty Rookie Draft Sleepers

There are no deeper rookie sleepers than players who weren’t even drafted in the NFL Draft — that’s right, we’re talking about undrafted free agents (UDFAs). The vast majority of UDFA players won’t make an NFL roster, let alone make a fantasy impact.

But there’s always a chance to strike gold. Recently, players like Adam Thielen, Austin Ekeler, Raheem Mostert and Jakobi Meyers have become weekly fantasy options despite not hearing their names called during the draft. I’ve identified seven UDFA players from the 2025 NFL Draft class who could join this list of fantasy sleepers turned studs. Let’s get started.

Raheim Sanders (RB – LAC)

This list is going to be running-back heavy for multiple reasons. For one, running backs are far more likely to become hits even after going undrafted, especially early in their careers, than any other position (except perhaps wide receivers). For two, this year’s running back class was so deep that some exciting prospects were bound to slip through the cracks.

One of those players was Raheim “Rocket” Sanders, a former South Carolina Gamecock who has now signed a deal with the Los Angeles Chargers. A big (217 pounds), fast (4.46-second 40) back with some receiving ability, Sanders profiles as exactly the kind of UDFA who could have an impact if things break the right way. He will have to beat out either 2024 sixth-rounder Kimani Vidal or special-teams specialist Hassan Haskins to make the Chargers’ active roster. No one should be surprised if he pulls it off.

Xavier Restrepo (WR – TEN)

Xavier Restrepo is by far the most surprising player to be eligible for this list. Every other player here had a consensus mock draft average draft position (ADP) of 200 or later — Restrepo’s was 137. With no public off-the-field concerns, it’s shocking the Miami product fell this far.

Restrepo even made my list of the top remaining prospects heading into Day 3 of the draft. I mentioned that as an unathletic slot specialist, Restrepo’s skill set may be more valuable to fantasy managers than real-life teams, and that same logic still applies now that he fell out of the draft completely.

Of course, the 23-year-old will need to get on the field before he can start (hopefully) using his route-running ability to rack up underneath targets. Thankfully, he’s landed in a decent spot to do that, as the Titans are lacking weapons at receiver outside of Calvin Ridley and the newly signed Tyler Lockett.

Tyler Boyd served as Tennessee’s primary slot receiver last season, and he is now a free agent. As a bonus, Restrepo was a college teammate of the Titans’ new franchise quarterback Cam Ward. Maybe that built-in chemistry will give him a higher chance of making an impact.

Marcus Yarns (RB – NO)

There are a lot of factors working against Marcus Yarns as a prospect. He attended a small school in Delaware, is undersized at 193 pounds and doesn’t have elite athleticism to make up for it with just a 4.45 40-yard time. With all that in mind, the fact that he was the top remaining running back on ESPN’s big board when the draft ended is impressive.

Perhaps Yarns’ secret weapon is his receiving ability, as he ranked 10th among FBS/FCS running backs in this class in Pro Football Focus’ (PFF) receiving grade. Having now landed in New Orleans, Yarns will have an uphill battle to make the roster behind Alvin Kamara, Kendre Miller and Devin Neal. But if we’re going to bet on UDFAs without guaranteed roster spots, they may as well be talented pass-catchers who may be going under the radar due to a lack of program pedigree.

Jake Briningstool (TE – KC)

When I said Restrepo was the only player on this list with a mock draft ADP below 200, I was only barely telling the truth, as Jake Briningstool’s consensus ADP was exactly pick 200. Briningstool isn’t likely to make a fantasy impact any time soon with Travis Kelce and Noah Gray in town.

However, the six-foot-six, 22-year-old product out of Clemson is the kind of tight end we like for fantasy — closer to a straight-up X receiver than an inline blocker. I don’t recommend spending a pick on a UDFA tight end, as even highly drafted tight ends often take multiple years to become fantasy-relevant. But if you’re going to, Briningstool is the best of the bunch.

Brady Cook (QB – NYJ)

Quarterbacks are similar to tight ends in the sense that UDFA hits from the position are few and far between. The leader since 2015 in fantasy points scored by an UDFA quarterback is Case Keenum, followed by Taylor Heinicke and Brian Hoyer. Those aren’t exactly inspiring names, but they did all have spurts of fantasy viability in Superflex dynasty formats. Cook could be the next player to follow in their footsteps.

A pocket-passing quarterback, Cook wasn’t particularly productive at Missouri, but he did post the lowest PFF turnover-worthy play rate of any quarterback in this class. He has also landed in a solid situation. With last year’s fifth-rounder Jordan Travis unfortunately retiring on Wednesday due to medical concerns, the only other quarterbacks on the Jets’ roster are Justin Fields, Tyrod Taylor and 2023 UDFA Adrian Martinez.

I wouldn’t call it likely, but there’s a foreseeable future in which Fields struggles, as Taylor turns 36 (this part is fairly likely), and Cook gets a shot in the last few games of the season with the Jets out of playoff contention. That’s a more realistic path to starting than I can see for any other UDFA quarterback in this class, so Cook gets the nod as my top pick.

Nick Nash (WR – ATL)

Nick Nash led all FBS receivers in receptions, yards and touchdowns in 2024. Yes, he did that on a terrible San Jose State team, so we have to take those numbers with a huge grain of salt. The NFL wasn’t too impressed either.

Nash is also older and less athletic than ideal, or even average. But I simply can’t look past all that production, and his landing spot in Atlanta isn’t terrible. Restrepo will be the popular pick (and likely overdrafted, if my early rookie drafts are anything to go by) for a UDFA wide receiver in dynasty rookie drafts, but Nash is my favorite.

Corey Kiner (RB – SF)

This pick is much more about the landing spot than it is about the player. Kyle Shanahan has a long history of turning UDFA running backs into fantasy producers, from the aforementioned Mostert, to Matt Breida to Jeff Wilson to Jordan Mason.

For now, Corey Kiner is buried on the 49ers’ depth chart behind Christian McCaffrey, Isaac Guerendo and fifth-round pick Jordan James. But we’ve certainly seen stranger things in San Francisco’s backfield than a guy who ranked 12th in this class in PFF run grade emerging as a playable option for a game or two.
