In August 2005, Rodgers agreed to a reported five-year, $7.7 million deal that included $5.4 million in guaranteed money and had the potential to pay him as much as $24.5 million if all incentives and escalators were met.

Rodgers spent his rookie season with the 4–12 Packers as the Packers' backup quarterback behind Brett Favre.
He received his first extended look in the opening preseason game against the San Diego Chargers after replacing Favre.
He had to endure a malfunctioning radio in his helmet and two offensive flags.

In his first NFL game, Rodgers completed two out of seven passes and was sacked twice.
He continued to struggle through the preseason, before ending the preseason by converting two third downs and throwing a touchdown pass to tight end Ben Steele against the Tennessee Titans.

Once the regular season began, Rodgers saw very little action that year.
He played against the New Orleans Saints in the fourth quarter of a 52–3 victory, and completed his first career pass to fullback Vonta Leach for 0 yards.
On December 19, 2005, Rodgers entered the game against the Baltimore Ravens at the end of the third quarter in a 48–3 loss.
He completed eight of 15 passes for 65 yards and an interception.
Rodgers saw one more play at the end of the season against the Seattle Seahawks, taking a knee to end the game.

Though Rodgers played very little in his rookie season, he ran the scout team during practice.
His job was to mimic opponents' schemes for the defense for the game the following week.
Rodgers said this was critical to his success, and that those were his game reps.
The defense and scouts often complained that he was practicing too hard, and at one point asked him to tone it down.
He stated that he had probably "rubbed people the wrong way" with how hard he practiced.
Wide receiver Donald Driver commented that Rodgers took "every scout-team possession like it was the last possession of his life."

After the Packers' losing season of Rodgers' rookie year, head coach Mike Sherman was fired and replaced by Mike McCarthy.
Rodgers was then placed in McCarthy's "Quarterback school" for six hours a day several times a week.
This focused on working on Rodgers' motor skills such as hand-eye coordination, finger dexterity, and mechanics.
McCarthy also worked on Rodgers' release point, moving it from right beside the ear hole of his helmet to further below it, to give him a smoother release.
Rodgers was also instructed to lower his body fat ratio from 15 percent to 12 percent.
Rodgers was resistant to the changes at first but later commented that he thought they were for the better.
During practice in 11-on-11 drills, Rodgers completed 62.7% of his passes with seven interceptions, and McCarthy commented that "He's getting better" and that "You're looking at a guy who's going to mature.
He's got athletic ability that people still haven't seen."

Favre did not attend the quarterback school under the new coaching staff and thus knew none of the terminology in the new system.
It was here that the friendship between Rodgers and Favre began to form as Rodgers instructed Favre which plays in the Sherman system corresponded to those in the new McCarthy system.
When the preseason began, Rodgers played as the backup in all four games; he completed 22 out 38 passes for 323 yards and three touchdowns.

Rodgers saw very little action during the 2006 season, but did step in on October 2 against the Philadelphia Eagles when Favre left the game due to injury.
Rodgers completed two out of three passes for 13 yards.
On November 19, 2006, Rodgers broke his left foot while playing against the New England Patriots in a 35–0 defeat at home, filling in for an injured Brett Favre, and Rodgers missed the remainder of the 2006 season.
Rodgers made a full recovery and was ready for the start of the 2007 season.
With then quarterbacks' coach Tom Clements, Rodgers reviewed every play from the previous season, learning to read defensive coverages and to throw receivers open.
Rodgers also took the spring practice reps with the Packers' first team.
