The 2024 NFL Combine is now in our rearview and only respective Pro Days stand in our way before the 2024 NFL Draft. Our 2024 Dynasty Rookie Rankings & SuperFlex Big Board, 2024 Dynasty Rookie Mock Drafts, and Rookie Scouting Reports are constantly updated after we gather more information about each rookie fantasy football prospect.
Below are our 2024 dynasty fantasy football rookie sleepers who shot up our Rookie Rankings & SuperFlex Big Board after balling out at the combine. These players have ascended into the back half of our rankings after being previously unranked or lower on the Big Board.
2024 DYNASTY ROOKIE SLEEPERS
ISAAC GUERENDO, RB, LOUISVILLE
There’s always one prospect that breaks the NFL Combine, and this year, it was Louisville running back Isaac Guerendo.
The Wisconsin transfer blistered the testing portion (9.98 RAS) at a beastly 6-feet, 221 lbs. He posted elite speed and explosion numbers with a 4.33 40-yd dash (24.08 MPH), 41.5″ vertical, and 10’09” broad jump 10’09”. He also tested great agility-wise with a 4.15 shuttle and 6.94 shuttle.
Most athletic RBs to participate at the Combine (Since 2000):

+ According to SPORQ Score
1 Jonathan Stweart (100.0)
2 A.J. Dillon (99.8)
3 Derrick Henry (99.7)
4 Doug Martin (99.5)
5 Saquon Barkley (99.4)
6 LaDainian Tomlinson (99.2)
7 Isaac Guerendo (99.1) pic.twitter.com/y4k3bDflES
The north-south, one-cut runner with serious burst and breakaway speed. However, he was the 1B at Louisville behind Jawhar Jordan (181 carries to 132 carries). Guerendo still produced, racking up over 1,000 total yards, averaging 6.1 yards per carry, and scoring 11 touchdowns. He’s also a reliable pass-catcher who can play on third down.
Isaac Guerendo sets a new record! 💪

150+ rushing yards and 3 touchdowns in a bowl game! @LouisvilleFB | @isaacguerendo pic.twitter.com/Jsh3ZKkzeD
Guerendo’s testing will significantly boost him on draft day, which should also make him a viable late-round target in dynasty rookie drafts. Based on measurables and athleticism alone, he’s an NFL running back.
TYRONE TRACY JR., RB, PURDUE
Tyrone Tracy Jr. began his collegiate career as a receiver at Iowa and finished his career as a running back at Purdue. The switch from mediocre wideout to high-upside running back gave him a shot at playing in the league. He quickly made his presence felt, both during his final season and at the combine.
After bulking up from 197 to 210 to play running back, he rushed for 716 yards and a Big Ten-leading 6.3 yards per carry. He also added 47 receptions for 330 yards, and another 428 kick return yards over his final two seasons at Purdue. His running back coach said he became the room’s best pass-protector, which kept him on the field for all three downs.
Purdue RB Tyrone Tracy Jr.

5'11" 209 lbs 👀
4.48 forty
6.81 3-cone (89th percentile)
4.06 short shuttle (93rd percentile) pic.twitter.com/nod0kQPwDc
At the NFL Combine, Tracy topped all running backs with a 6.81-second 3-cone and finished second-best in the shuttle (4.06s) and vertical jump (40″). He also ran a 4.48 40-yard dash to finish eighth, and his 10-yard split (1.53s) was sixth.
Tracy’s untapped potential, versatility as a runner and receiver, and elite athleticism for his position will make him an intriguing late-round dynasty flier.
JOHNNY WILSON, WR, FLORIDA STATE
Johnny Wilson is one of the most polarizing players in this class. He’s built like a tight end, but played receiver at Florida State and did the same at the NFL Combine.
Wilson will be a red zone monster in the league. He stands at 6-foot-6, 231 lbs, with 35 5/8″ arms and an 84 1/2″ wingspan (99th percentile). Not only does he have the length of a pterodactyl, but he also has speed and agility, making it a challenge for defenders to cover on the perimeter and in the slot.

The thing about his size and strength is that he could legitimately be this class’ TE2 behind Brock Bowers if his future team moves him there. Still, his elite catch radius, high-point ability, YAC upside, and non-stop motor in the blocking game make him a three-down weapon in the NFL.
Top short shuttle WR times:
— Dane Brugler (@dpbrugler) March 3, 2024
4.02 Luke McCaffrey
4.03 Rome Odunze
4.05 Ricky Pearsall
4.11 Johnny Wilson
4.16 Anthony Gould
4.18 Jalen McMillan
4.31 Troy Franklin
4.32 Jacob Cowing
4.35 Tulu Griffin
The fantasy upside is massive here — especially if he moves to tight end.
BUB MEANS, WR, PITTSBURGH
The COVID/NIL Era of college football has made this draft class one of the more interesting classes of all time. It has a bunch of typical early entries, but it’s full of fourth, fifth, and even sixth-year players who transferred a time or two and further developed their craft. However, did those late bloomers hit their ceiling in college? Or is there untapped potential because they were finally given a chance?
Bub Means falls into the latter category as a fifth-year senior.
Means started his career as a cornerback at Tennessee before transferring to play receiver at Louisiana Tech and then finishing his time at Pitt. Over his final two seasons at Pitt, he had 68 receptions for 1,122 yards (16.5 avg) and eight touchdowns. In 2023, he utilized that speed by only trailing Rome Odunze (43) with 34 targets of 20-plus yards.
The top-5 "Flying 20" times (second half of the 40-yd dash) among the WRs at the Combine (anything under 1.8 is elite):
— Dane Brugler (@dpbrugler) March 10, 2024
1.78 – Brian Thomas Jr.
1.78 – Xavier Leggett
1.79 – Xavier Worthy
1.83 – Troy Franklin
1.83 – Bub Means
Measuring in at 6-foot-1, 212 lbs with massive hands (10⅛ inches) and long arms (33¼ inches), he proved he is one of the better athletes at his position by running a 4.43 40-yard dash and recording a 39½-inch vertical at the NFL Combine.
We frequently get calls from NFL scouts about players they want to see in Mobile and that’s happened couple times already with @Pitt_FB WR Bub Means (6007v, 218v, 33 1/4 arm).
— Jim Nagy (@JimNagy_SB) September 9, 2023
La. Tech transfer @twoplayaBub is type of HWS receiver that plays on Sundays and ST coaches will love… pic.twitter.com/EqI1SDaMCd
Means may be on the older side, but he’s still relatively raw as a receiver and should only get better from here. The upside is real.
JALEN COKER, WR, HOLY CROSS
Jalen Coker was an FCS legend at Holy Cross, but he put himself on the map during the pre-draft process, showing he belonged with elite FBS athletes.
Coker tested well at the combine, especially for a small school receiver, scoring a 9.46 RAS. He particularly shined as an explosive athlete with a combine-best 42.5″ vertical, an elite 10’8″ broad jump, and an impressive 10-yard split (1.52) on his 40-yard dash (4.57).
WHAT A CATCH BY JALEN COKER @HCrossFB pic.twitter.com/CH2NnBcEGP
— CBS Sports College Football 🏈 (@CBSSportsCFB) January 13, 2024
Coker stood out at Holy Cross, leaving the program as the all-time leader in touchdown receptions (31) and receiving yards (2,715). As a senior, he broke the program record for 15 receiving touchdowns and finished his final season with 1,040 yards on 59 receptions.
Coker’s blend of hops, strong hands, and body control makes him a prototypical X receiver in the NFL and a future fantasy asset.
ISAIAH WILLIAMS, WR, ILLINOIS
If we want to go even deeper at the receiver position, Isaiah Williams, the shifty slot receiver from Illinois, is your guy. Standing at only 5-foot-9 and 182 lbs, the explosive athlete will make his mark as a tough slot receiver in the NFL.
Unfortunately, he did not test well in the 40 (4.63s, slowest WR in his class) and will test it again at Illinois Pro Day. However, he lit it up agility-wise (6.75 3-cone, third-best) and showed great explosiveness (38″ vertical and 10’03” broad jump). As shown on his tape, he crushed the gauntlet, reaching 19.04 MPH (fifth-fastest), proving his play speed is greater than his track speed.
Keon Coleman reached a top speed of 20.36 mph during the gauntlet drill, the fastest speed by any receiver over the last two seasons.

At Illinois, he spent his first two seasons at quarterback before making the switch to receiver. Even with no experience, he immediately became the team’s best receiver, grading high on PFF over his final three seasons (72.5, 74.9, 79.9). He increased his production and got better each year, capping his final season with 82 receptions for 1,055 yards and five touchdowns in 12 games. He also posted an exceptional 80.9 PFF receiving grade and 2.51 yards per route run.
Williams will be a chain-mover in the league and a future starting slot, who’s fun and shifty after the catch.
THEO JOHNSON, TE, PENN STATE
The Penn State specimen is not a true “sleeper” because he was already ranked as my TE6 before the NFL Combine, but his performance at the combine bumped him up the overall SuperFlex Big Board.
Theo Johnson showcased his athleticism with a remarkable 9.99 RAS, the best among his position at the 2024 NFL Combine and the second-highest ever recorded at TE. His sheer size and athleticism create an advantage against opposing defenders. However, he was not utilized much in Penn State’s conservative offense, finishing his four-year career with 77 receptions for 938 yards and 12 touchdowns.
Theo Johnson is a TE prospect in the 2024 draft class. He scored an unofficial 9.99 #RAS out of a possible 10.00. This ranked 2 out of 1105 TE from 1987 to 2024.

Splits projected, Shuttle would have kept him that 10.00, but Cone lost it.https://t.co/HuWxnxJn85 pic.twitter.com/sjJ15iseny
Based on his athletic profile alone, Johnson should have a better pro career than college career. His game has clear holes, but if drafted into a creative offense that uses its tight end, he could shine in the NFL.
JARED WILEY, TE, TCU
Jared Wiley is one of the better fantasy tight end prospects in this class because he’s arguably the best pure pass-catcher of the bunch. He’s a big target at 6-foot-6, 250 lbs with 33 1/4″ arms. He also performed well at the combine with the third-best vertical (37″), fifth-best 40-yard dash (4.62s), and sixth-best 3-cone (7.19s).
I've been in on TE Jared Wiley since the Senior Bowl. 6'7", 255-260 lbs. Moves like a smaller man. Solid blocker. Projected between rounds 4 and 5. Could he slide into the top-100? pic.twitter.com/l0tCZWHIZW
— Mike Giardi (@MikeGiardi) March 1, 2024
TCU found ways to move him around the formation from in-line (202 snaps in 2023) to the slot (121). He also finished 2023 with a solid 74.8 PFF receiving grade and only had one drop on the year. Wiley is a high-upside pass-catching tight end who could find himself as a weekly fantasy streamer option at a volatile position.
