The 2025 NFL season is set to deliver fantasy football fireworks, with breakout stars and sleeper picks poised to shake up draft boards. Second-year phenoms like Drake Maye and Marvin Harrison Jr. headline a deep class of potential league-winners, while undervalued veterans could provide championship-winning value.

This year’s sleepers may prove even more crucial than usual after last season’s unprecedented surge of unexpected fantasy stars. From rookie tight ends with red-zone dominance to running backs primed for expanded roles, identifying the right late-round targets will separate contenders from pretenders.

With multiple NFC teams facing favorable schedules and several franchises positioned for dramatic turnarounds, 2025 promises to be one of fantasy football’s most unpredictable and rewarding seasons yet.

ESPN Fantasy Football 2025: Top Breakout Candidates and Sleeper Picks to Target for NFL Season Success

Second-Year Players Poised for Fantasy Stardom in 2025

The 2025 fantasy football season presents a golden opportunity for second-year players to make their mark. Drake Maye, now entering his sophomore campaign with the Patriots, has shown tremendous growth during offseason programs, displaying improved decision-making and deep-ball accuracy. His connection with veteran WR Kendrick Bourne could become one of the NFL’s most productive QB-WR duos.

Meanwhile, Marvin Harrison Jr. is expected to explode in Arizona’s high-powered offense. With Kyler Murray fully healthy and the Cardinals implementing more spread concepts, Harrison could challenge for the receiving yards crown. Fantasy managers targeting these second-year stars in mid-rounds may secure league-winning value.

Don’t overlook the sophomore slump phenomenon. While these players have tremendous upside, history shows about 30% of breakout candidates disappoint in Year 2. Balance risk by pairing them with stable veterans.

Top 5 Second-Year Breakout Candidates

Rookie Fantasy Sleepers Who Could Outperform Their ADP

The 2025 draft class features several under-the-radar talents who could deliver fantasy value beyond their current average draft positions. Tetairoa McMillan stands out particularly in PPR formats, with Arizona’s offense tailored to maximize his skills. His precise route-running and ability to create yards after catch make him an ideal late-round WR4 with WR2 upside.

Among running backs, Jaydon Blue has quietly climbed depth charts during training camp. While not getting the same attention as first-round RBs, Blue’s combination of vision and receiving ability makes him a perfect fit for Houston’s zone-running scheme. If incumbent Dameon Pierce struggles early, Blue could seize a significant role by midseason.

Remember the “third-round RB rule”—historically, RBs drafted in Round 3 have a 42% higher chance of becoming fantasy relevant compared to other rounds. Blue fits this profile perfectly.

Veterans Being Undervalued in ESPN Fantasy Drafts

While shiny new toys dominate fantasy conversations, several proven veterans are slipping too far in ESPN drafts. Kirk Cousins continues to be one of fantasy’s most consistent QB values, yet he’s routinely available after QB15 despite never finishing worse than QB12 in full seasons with Minnesota. His move to Atlanta reunites him with offensive coordinator Zac Robinson, who helped Matthew Stafford produce a career year in 2024.

At running back, James Conner remains undervalued despite clear RB1 usage in Arizona. While managers chase younger options, Conner’s goal-line dominance and pass-catching role make him a steal in Round 5-6. Last season, he ranked 7th among RBs in red zone touches per game—a statistic that often predicts fantasy success.

Undervalued Veterans by Position

• QB: Geno Smith (QB20 ADP, QB12 ceiling)
• RB: James Conner (RB24 ADP, RB15 potential)
• WR: Mike Evans (WR28 ADP, WR18 upside)

Fantasy Playoff Schedule Analysis: Teams to Target

A critical yet often overlooked drafting strategy involves analyzing fantasy playoff schedules (Weeks 15-17). The Detroit Lions face the easiest playoff schedule for fantasy QBs, with matchups against Chicago, Buffalo, and Minnesota—all bottom-10 defenses against QBs last season. This makes Jared Goff an excellent QB2 target with streaming upside.

Conversely, the Philadelphia Eagles face the toughest WR schedule during fantasy playoffs, facing Jalen Ramsey, Sauce Gardner, and Jaycee Horn in consecutive weeks. While AJ Brown and Devonta Smith are still must-starts, this warrants consideration when drafting Eagles pass-catchers at their premium ADPs.

Schedule analysis matters most for fringe starters and streaming options. Elite talents overcome tough matchups—focus on schedule when debating players of similar tiers late in drafts.

Potential Late-Round Tight End Values

The tight end position remains fantasy’s most challenging to navigate after the elite options. Juwan Johnson presents intriguing upside as Derek Carr’s safety valve in New Orleans. Last season, Carr targeted TEs on 26% of his passes—third-highest among starting QBs. With improved offensive line play, Johnson could see increased red zone opportunities.

For those waiting until the final rounds, Noah Fant benefits from Seattle’s new quick-pass offense under coordinator Ryan Grubb. Fant’s athletic profile (4.50 40-yard dash at 249 lbs) matches perfectly with concepts that made Gerald Everett productive in this system last season.

TE Sleepers Ranked by Upside

1. Juwan Johnson (NO)
2. Jelani Woods (IND)
3. Noah Fant (SEA)

Running Backs at Risk of Losing Their Starting Jobs

The NFL’s move toward committee backfields creates constant volatility at the RB position. Alvin Kamara enters the season at age 30 with Kendre Miller waiting in the wings. While Kamara remains efficient in the passing game, his declining yards per carry (3.9 in 2024) suggests diminishing rushing upside.

In Houston, Joe Mixon faces unexpected competition from Dameon Pierce, who has reportedly regained burst after an injury-plagued 2024. The Texans’ new zone-blocking scheme favors Pierce’s one-cut running style, creating a potential timeshare that could cap Mixon’s ceiling.

When drafting veteran RBs, always handcuff them with their presumed successors. The $2 you spend on Kendre Miller could save your season if Kamara declines or gets injured.
