Rookie quarterbacks Fernando Mendoza and Drew Allar delivered standout performances, while a controversial signing looms for the Seattle Seahawks.

The NFL offseason has officially entered its next phase, with all 32 teams now deep into training camp. News continues to emerge rapidly as the league gears up for its first full week of preseason games.

Thursday night's initial preseason action delivered significant excitement, largely thanks to several impressive rookie performances. Quarterbacks Fernando Mendoza and Drew Allar particularly shone, capturing fan attention with their debuts.

While veterans like Kirk Cousins and Jacoby Brissett also had solid outings, the evening was dominated by fresh talent and a notable off-field development regarding cornerback Terrion Arnold's expected move to the Seattle Seahawks, according to reporting by Yahoo Sports - NFL.

Rookie Quarterbacks Spark Excitement in Preseason Debuts

Fernando Mendoza, the No. 1 overall pick, made a strong first impression for the Las Vegas Raiders in the preseason opener. He completed 10 of 16 pass attempts for 96 yards and one touchdown, showcasing why he was a top selection. A particularly impressive play involved Mendoza delivering a 19-yard pass to Malik Benson between three Cardinals defenders, a throw that evaded veteran linebacker Jack Gibbens.

On the other side of the field, Pittsburgh Steelers' 2026 third-round rookie Drew Allar stole the show, especially in the second half. Allar went 10-of-13 passing for 153 yards and two aerial touchdowns, adding a third score with a run at the goal line. His stellar performance, which included a 75-yard connection with fellow rookie Kaden Wetjen, led the Steelers to a 28-9 victory over the Green Bay Packers. While Mason Rudolph started and Will Howard also played, Allar's dynamic entry in the third quarter left a lasting impact.

Veterans and Other Rookie Standouts Impress

Experienced quarterbacks also had their moments on Thursday night. For the Las Vegas Raiders, veteran Kirk Cousins had a solid debut, completing 5 of 6 passes for 50 yards and a touchdown. He earned an impressive 141.0 NFL passer rating in his limited preseason action.

The Arizona Cardinals saw a perfect opening drive from Jacoby Brissett, who completed all five of his pass attempts. His lone drive concluded with a touchdown pass to Marvin Harrison Jr., offering an encouraging start for the team.

Beyond the quarterbacks, No. 3 overall pick running back Jeremiyah Love showcased his potential for the Green Bay Packers. Love tallied 73 scrimmage yards, displaying toughness and even a highlight-reel hurdle in his professional debut.

Off the field, news broke concerning cornerback Terrion Arnold, who is reportedly expected to sign with the Seattle Seahawks.
