As NFL teams gear up for the 2025 preseason, attention naturally gravitates toward first-round picks and high-profile rookies. Yet, some of the most intriguing storylines may come from the league’s most underrated rookies players who slipped through the draft cracks or arrived with little fanfare but possess the talent and drive to make an immediate impact. These under-the-radar rookies often provide crucial depth, special teams contributions, and occasionally emerge as surprise starters. Here’s a look at several underrated rookies to watch closely this preseason, backed by stats, scouting insights, and team contexts.
Seth Henigan, QB, Jacksonville Jaguars
Despite an impressive college career at Memphis, where Henigan started all 50 games and set an AAC record with 14,266 passing yards, he went undrafted in 2025. Standing 6’3” and weighing 215 pounds, Henigan combines solid mechanics with excellent decision-making and pocket awareness. His quick reads and ability to place the ball precisely make him a promising backup option behind Trevor Lawrence. Jaguars insider Tom Pelissero notes, “Henigan’s accuracy and poise in the pocket could earn him a roster spot, especially given Jacksonville’s need for QB depth”. His preseason reps will be critical to prove he can transition his college success to the NFL level.
Elijah Simmons, DL, Arizona Cardinals
At 334 pounds, Simmons is a nose tackle who flew under the radar at Tennessee due to a deep defensive line rotation. Though he started only two games in college, Simmons consistently disrupted offenses with his strength and ability to hold the point of attack. The Cardinals have invested heavily in their defensive front this offseason, and Simmons could carve out a role in their rotation. Defensive analyst Dame Parson highlights Simmons’ “rare combination of size and quickness,” making him a sleeper to watch in Arizona’s camp.
Keleki Latu, TE, Buffalo Bills
Latu, an undrafted free agent from Washington, is a towering 6’7” tight end with a large catch radius. Last season, he posted career highs with 40 receptions for 371 yards, showcasing reliable hands and solid route-running despite not being an elite athlete. With Dawson Knox aging and Dalton Kincaid’s rookie deal nearing its end, the Bills are keen to develop tight end depth. Latu’s size and ability to work the middle of the field could earn him snaps in Buffalo’s offense, especially in two-tight end sets.
Jacolby George, WR, Carolina Panthers
George’s path to the NFL is defined by versatility and special teams value. At Miami, he caught 110 passes for 1,616 yards and 16 touchdowns over two seasons, proving competitive despite lacking elite speed. His 13.5-yard punt return average in college makes him a dual-threat weapon. Panthers coaches see George as a potential slot receiver and special teams contributor, a critical role for undrafted rookies fighting for roster spots. “His shiftiness and competitiveness give him a real shot to make the 53-man roster,” says scout Dame Parson.
Other Notables to Watch
Several other undrafted rookies have generated buzz during minicamps and OTAs. Cornerback Cobee Bryant (Falcons) and safety Shilo Sanders (Buccaneers) bring athleticism and football IQ that could translate into early playing time. Quarterback Brady Cook (Jets) and receiver Elijhah Badger (Chiefs) also have intriguing skill sets that could push them into rotational roles.
Why These Rookies Matter
Underrated rookies like Henigan, Simmons, Latu, and George embody the unpredictable nature of NFL roster building. They remind us that draft status isn’t destiny work ethic, scheme fit, and opportunity often dictate success. As NFL analyst Rob Rang puts it, “Every year, undrafted free agents turn heads in training camp and preseason, forcing teams to rethink their depth charts”.
With training camps underway, these underrated rookies will be eager to prove their worth, making the 2025 preseason an exciting time for fans who appreciate the hidden gems of the NFL. Keep an eye on their progress some could emerge as key contributors when the regular season kicks off.
