The Most Improved NFL Players at Every Position in 2025

The NFL season is full of storylines, but one of the most compelling is how players develop from year to year. In 2025, Pro Football Focus identified a group of players across the league who took significant steps forward, becoming key contributors for their teams. Improvement in the NFL is not just about raw statistics found on https://sportsbook.draftkings.com/leagues/football/nfl; it is also about impact on the field, efficiency, and growth in areas that matter like pass protection, tackling, or coverage. Using advanced metrics and grades, we’ve highlighted the players who have made the biggest strides at each position heading into or during the 2025 season.

Improvement at every position can change an offense or defense, helping teams compete more effectively. Below, we break down the players who rose in rankings and expanded their roles, often becoming foundational pieces for their teams.

Quarterback: Caleb Williams

At quarterback, PFF sees Chicago Bears signal-caller Caleb Williams as one of the most improved players going into 2025. After a challenging rookie season marked by sacks and mixed performance, Williams entered the year with new coaching and improved protection upfront. The Bears added veteran linemen and adjusted their offense to better showcase his strengths, which translated to more consistent play and growth in his performance.

Running Back: Emerging Playmakers

Younger backs who see increased opportunity often take big steps forward. In 2025, a back like Jaylen Wright of the Miami Dolphins was positioned for a breakout with more touches and better blocking ahead of him. Consistent opportunity paired with natural talent pushed his growth forward.

Wide Receiver: Marvin Harrison Jr.

The Cardinals’ star wide receiver has long been touted as a future great, and in 2025, he elevated his game even further. After a promising rookie season, he began producing more reliably downfield and became a primary target in the offense, improving route running, separation, and production.

Tight End: The Giants’ Theo Johnson

At tight end, players like Theo Johnson of the New York Giants showed growth as more consistent contributors. After splitting time and showing flashes in his first season, Johnson’s role expanded, allowing him to make more plays in both the passing game and blocking schemes.

Offensive Line Breakouts

Offensive linemen often fly under the radar, but improvement in the trenches can define entire offenses. Peter Skoronski of the Tennessee Titans, playing guard after earlier struggles, took meaningful steps forward in pass blocking and run support. Similarly, Jackson Powers-Johnson at center for the Raiders settled into his role, anchoring the interior line with improved grades and fewer pressures allowed.

Defensive Tackle: Jer’Zhan Newton

On the defensive line, younger players like Jer’Zhan Newton of the Washington Commanders began showing flashes of their potential. While still developing, players like Newton improved their pressure rates and overall impact, providing coaches with more confidence to deploy them in key situations.

Edge Rusher: Kayvon Thibodeaux

Pass rushers often define defensive success, and Kayvon Thibodeaux of the New York Giants returned to a higher level of play late in the season. After earlier struggles, he finished strong with increased pressures and better edge play, proving that growth is possible even after a slow start.

Linebacker: Tyrice Knight

At linebacker, players like Tyrice Knight of the Seattle Seahawks made notable strides. Knight improved his tackling and pass-rush contributions, carving out a larger role in a defense that needed production from versatile players in multiple fronts.

Cornerback: Kool-Aid McKinstry

Cornerbacks often take time to mature, and Kool-Aid McKinstry of the New Orleans Saints stepped into a starting role and held his own. By earning higher coverage grades and showing playmaking potential, McKinstry demonstrated that younger corners can become reliable starters.

Safety: Javon Bullard

In the secondary, Javon Bullard of the Green Bay Packers grew by excelling in run support and awareness. As safeties diversify their roles in modern defenses, Bullard’s tackling ability and instincts helped him justify increased playing time and responsibility.

Across the NFL, these improvements show how player development can shift a team’s outlook. Unlike purely statistical leaders, most improved players are evaluated on multiple metrics, including PFF grades, which quantify performance beyond the box score. Players who excel at protecting the quarterback, disrupting opposing offenses, or consistently executing their assignments at a high level provide value that is sometimes invisible in traditional statistics.

The Broader Impact

Progress in performance often parallels team success. A quarterback who makes strides early in the season can stabilize an entire offense. Boosts in offensive line play improve quarterback health and rushing attack effectiveness. Young defensive stars can elevate unit performance by providing turnovers, pressure, or lockdown coverage. Fundamental improvement across multiple positions is why teams invest heavily in coaching, analytics, and player development.

These players represent a mix of rising stars and underrated contributors turned difference makers. Some were predicted to improve before the season started, while others emerged as surprises based on in-game performance and advanced grades.

Recognizing improvement highlights the fluid nature of the NFL. Veteran players can refine techniques, while young players adjust to the speed and complexity of the professional game. In a league defined by parity, rising performance at key positions often separates playoff teams from the rest.

As fans and analysts reflect on the 2025 season, these most improved players underscore the truth that development is one of the most exciting parts of football. Their journeys from solid performers to significant contributors tell the story of growth, opportunity, and adaptation in the NFL world.
