Most NFL rookies do not immediately succeed after transitioning from college football. Each player is on a unique developmental trajectory, and the investment in their growth can vary considerably. However, some rookies do make a significant impact in their first year. Notably, Washington Commanders quarterback Jayden Daniels exceeded expectations by starting on Day 1, throwing for over 3,500 yards, leading his team in rushing, and helping them reach the NFC Championship Game. While such performances are the exception rather than the norm, they set a high bar for those entering their second year.

As players move into their second professional season, the expectations increase significantly due to a year’s experience in the system and a full offseason to refine their skills. The most pressure falls on recent first-round draft picks, who are anticipated to become game-changers. Moneyline has identified eight key selections from the 2024 NFL Draft, including three quarterbacks, who need to demonstrate marked improvement in the upcoming 2025 season to avoid potential discussions about their future with the team. Among these players is Caleb Williams, who was initially hesitant about joining the Chicago Bears. After a pre-draft visit, he expressed his readiness to help the Bears succeed, but he faced challenges under the former coaching staff.

Under new head coach and play-caller Ben Johnson, Williams is expected to show significant growth. General manager Ryan Poles has surrounded him with talent, enhancing the offensive line with the acquisitions of Joe Thuney, Drew Dalman, and Jonah Jackson, while also drafting tight end Colston Loveland and wide receiver Luther Burden III. To live up to the expectations, Williams must solidify his understanding of the game, refine his footwork, and execute precise timing with his throws. His development will inevitably be compared to that of Jayden Daniels, the quarterback drafted just one spot before him.

Another player under scrutiny is Michael Penix Jr., selected by the Atlanta Falcons as the eighth overall pick. The Falcons entered the draft after signing veteran quarterback Kirk Cousins, who was soon benched by Week 16 of the season, paving the way for Penix to take the helm. In his limited appearances, Penix showed promise, completing several impressive passes despite a lower pass completion percentage overall. The Falcons coaching staff noticed his ability to read defenses effectively, essential for the development of a franchise quarterback. As Atlanta boasts a strong supporting cast, the onus is on Penix to prove himself worthy of leading the team into the playoffs after a six-year hiatus.

J.J. McCarthy’s situation with the Minnesota Vikings resembles that of the team's previous starter, Sam Darnold. The Vikings traded up to select McCarthy with the tenth overall pick after a promising college career, but he suffered a knee injury that sidelined him during his rookie season. Darnold performed admirably, leading the team to a strong 14-3 record, but he left for the Seattle Seahawks in free agency. Head coach Kevin O'Connell now expects McCarthy to maintain the level of play established during Darnold's season. McCarthy expressed confidence in his preparation, emphasizing his support from teammates and coaching staff alike as he strives to command the offense.

Marvin Harrison Jr. entered the league with high expectations but had a mixed rookie season. Recognized as one of the best wide receiver prospects in recent years, he still identified areas for improvement, particularly regarding his physical readiness for the NFL. Although he recorded a respectable number of catches and touchdowns, he aims to increase his production in Year 2. Harrison's success will depend on how well the Arizona Cardinals coaching staff can integrate him into the offense effectively, moving him around the formation to exploit matchups.

The Pittsburgh Steelers had plans for rookie Troy Fautanu to secure the right tackle position last season, but injuries derailed those ambitions. After suffering an MCL sprain and later a dislocated kneecap, Fautanu's first season was limited. Nevertheless, with starting left tackle Dan Moore Jr. departing, the Steelers will rely on Fautanu to solidify the offensive line alongside Broderick Jones, who is expected to switch positions. The Steelers' quarterback situation remains a concern, with either an aging Aaron Rodgers or another lesser option under center. Therefore, Fautanu's development is critical for establishing a reliable offensive unit.

Jordan Morgan, last year's 25th overall pick by the Green Bay Packers, is also poised to make a crucial transition. After beginning his career as a guard, he is now in contention to start at left tackle, a position he played extensively in college. With his athleticism and technique, returning to tackle could mitigate some of the durability concerns he faced. The Packers have a youthful and dynamic offense centered around quarterback Jordan Love, and Morgan's ability to protect Love’s blind side effectively could be pivotal as the team looks forward to enhanced performance in the coming seasons.

Laiatu Latu of the Indianapolis Colts entered the league under considerable pressure following his selection as the 15th overall pick. Although he registered four sacks during his rookie season, he was outperformed by other rookies in the defensive category. The Colts' coaching staff is optimistic about Latu's potential for growth in his second year, especially following the departure of starter Dayo Odeyingbo. The team's defensive strategy will rely on Latu rising to expectations and proving his worth to the organization.

Lastly, Dallas Turner of the Minnesota Vikings is also looking to make his mark in Year 2. Having experienced limited playing time as a rookie, the Vikings recognize his potential and have high hopes for his development. As the team enhances its defense with new talent, Turner's opportunity to contribute significantly increases. His growth will be essential as Minnesota strives for improved performance in a highly competitive league.
