If you were to ask fellow dynasty fantasy football owners what the one wide receiver they’d like to have on their team the most is, one of the top names you’re likely to hear is Puka Nacua. It’s been an incredible ride for a receiver that went largely undrafted in rookie fantasy football drafts back in 2023. Nacua is just one example of a player who fell below the radar, and whoever was the first to pick him up reaped the rewards.
This year, the draft class is widely viewed as weak, but it still has some possible diamonds in the rough. While they probably won’t reach the level that Nacua has reached, they could still possibly be the difference between a fantasy football championship and falling just short over the next few years.

Deep Dynasty Fantasy Football Sleepers to Pick Up Now
Corey Rucker, WR, Las Vegas Raiders
Every year, there are a handful of prospects who get criticized for the conference they play in. Another example of this is Corey Rucker out of Arkansas State. Rucker spent five years in college but is still relatively young, at 23 years old. He spent his first two seasons at Arkansas State, where he made a name for himself when he set a freshman record with 310 receiving yards in a game against Louisiana-Monroe. His transfer to South Carolina didn’t get him much playing time, so he returned home to Arkansas State for his final three seasons. All he did in his final two seasons was post back-to-back 1,000-yard campaigns in just 13 games both times.
Rucker may not be the best receiving prospect that’s ever been seen, but he joins a Las Vegas Raiders team completely devoid of talent. Jalen Nailor is the WR1 and Jack Bech is the WR2, so Rucker climbing his way up the ladder from undrafted free agent to starter would not be at all surprising. With good speed, size and high potential, he has as good a chance as most receivers in this class to make an immediate impact.
Jeff Caldwell, WR, Kansas City Chiefs
Sometimes those who take the unconventional road reap the rewards. That couldn’t be truer for Cincinnati product Jeff Caldwell. After undergoing a nine-inch growth spurt before his senior year of high school, Caldwell still had little attention from college schools and attended FCS school Lindenwood, as they were the only school to extend him an offer. In 2023, he was named to the first-team all-conference, and in 2024, he racked up over 1,000 receiving yards and 11 touchdowns on just 53 catches. He was a second-team All-American that same season and was a finalist for the Walter Payton Award (best FCS offensive player).
Although he didn’t do too much last year at Cincinnati, there’s a reason he’s being included in this conversation, and it’s due to how much of a freak athlete he is. Believe it or not, he actually ranks higher on RAS scoring than the most talented receiver of all time, Calvin Johnson.
Just being a freak athlete in itself doesn’t mean jack. Just ask the Cincinnati Bengals about John Ross III. However, Caldwell’s situation is much different, with him landing with the Kansas City Chiefs. Not only does he come into a receiving corps that needs talent more than bald men need the country of Türkiye, but he will have Patrick Mahomes throwing him the ball. You know, the guy who is arguably on track to be the best quarterback of all time.
There is no guarantee that Caldwell will work in the NFL, but this kind of athletic profile, paired with one of the best quarterbacks ever, is worthy of some FAAB as a deep fantasy football sleeper.
Le’Veon Moss, RB, Miami Dolphins
There are some players who just can’t get it going in the collegiate ranks, but somehow find a way to break onto the scene in a big way in the NFL. These players are few and far between, but Le’Veon Moss may turn into the next prime example. He struggled with injuries during his tenure at Texas A&M, but he was incredibly effective when he was on the field.
Moss averaged five and a half yards per carry during his career and posted two seasons with 10 or more rushing touchdowns, even when he played a combined 18 games during that time.
He is a big back who excels at muscling his way into the end zone in goal-line situations. He scored on 12 of his last 16 goal line carries over the last two seasons and now joins a backfield with De’Von Achane. Moss would easily bring the brawn that would complement Achene’s speed. His ability to win that RB2 role also won’t be too difficult in a backfield that sees his competition consist of Ollie Gordon, Jaylen Wright and Donovan Edwards. It wouldn’t be at all surprising if Moss becomes one of the most beloved or hated (depending on if you own him) vultures in all of fantasy football, earning his spot on this list of deep fantasy football sleepers.
