I agree with all of this - doesn't mean I'm glad to see Jones go, but entering his age 30 season he's coming off a year where he basically wasn't healthy and productive until the last month of the regular season + playoffs. He had a great game in Week 1, tweaked a hammy, and wasn't a difference maker until December last season. His resurgence coincided with the Packers turning things around offensively, sure, but replace him with a different established NFL RB and that field full of young receivers/TEs and a young quarterback figuring it out and I think the Packers still play pretty well.
I think the lack of 100 yard games to Jones' resume has more to do with the Packers trying to limit wear and tear on a slight running back based on his injury history - Jones isn't a big guy, he can be a difference maker in the NFL when he's healthy...but if a team feeds him close to 20 carries a game he's gong to get hurt.
When Jones 1st signed that contract, people viewed it as a 1-2 year deal where he'd become a cap casualty after the 2021 or 2022 seasons...the Packers found a way to play cap gymnastics and get one more season out of him before opting to let him walk into the sunset of his career this offseason based on the hard reality of the NFL as a business.
