Aaron Rodgers' discontent in Green Bay dates back to last year but centres around the Packers' philosophy rather than Jordan Love, he said on Monday.
Reigning NFL MVP Rodgers is pushing to leave the team he has represented since 2005.
Reports of his unhappiness first emerged on draft day this year, but there was no late trade as five quarterbacks went in the first round – including three in the top three.
While Rodgers is a three-time MVP, one-time Super Bowl MVP and one-time champion, he had a career-high 48 touchdowns en route to individual recognition in 2020.
The 37-year-old also had his highest completion percentage since becoming a starter (70.7) and a passer rating of 121.5 that he only previously surpassed in 2011 (122.5).
This came after a draft in which the Packers selected QB Love with their first-round pick, rather than providing support to Rodgers.
However, discussing his desire to depart Green Bay on SportsCenter, the veteran said: "With my situation, look, it's never been about the draft pick, picking Jordan.
"I love Jordan; he's a great kid. [It has been] a lot of fun to work together."
Love did not take a single snap last year but is widely considered the man to take the reins when Rodgers eventually moves on.
The Packers great hopes that will be sooner rather than later.
Rodgers, who spent the offseason working on quiz show Jeopardy! and reportedly has an interest in keeping the role long-term, explained his reasoning as he confirmed a report he was skipping voluntary organised team activities.
"I love the coaching staff, love my team-mates, love the fan base in Green Bay," he said. "[It has been] an incredible 16 years.
"It's just kind of about a philosophy and maybe forgetting that it is about the people that make the thing go. It's about character, it's about culture, it's about doing things the right way.
"A lot of this was put in motion last year, and the wrench was just kind of thrown into it when I won MVP and played the way I played last year.
"This is just kind of, I think, a spill-out of all that. But it is about the people, and that's the most important thing. Green Bay has always been about the people."
Rodgers, who has three years left on his contract and will count for $37.2million against the cap in 2021, ranks 11th all-time for passing yards, although he is only 230 shy of catching John Elway and breaking into the top 10.
Meanwhile, his 412 TDs rank seventh, with Rodgers having thrown more than 1,500 passes fewer than every other QB with over 400 scores.
A touchdown percentage of 6.3 ranks fifth among players with 50 or more games, with Rodgers' next regular season appearance set to be his 198th.
The Packers start the new season at the New Orleans Saints on September 12.
