I believe that Benson is "fools gold." He is essentially a 2-year experience RB. He was injured in practice prior to the 2020 season. He missed the entire 2020 season and essentially missed the 2021 season except for 6 snaps.
In 2022 and 2023, he came back with ~900 yds on ~11 carries/game (~155 carries/season). Average runs in an NFL game varies slightly from season to season, like all stats do. In 2022 (last year) a typical team ran 63 plays a game, averaged 27.3 rushes per game. The primary RB typically accounts for ~2/3 rds of the carries (closer to ~250-300 carries/season).
What is most important in this equation is not as much his stats as the nature of his injury. December of 2020, Benson suffered a devastating knee injury that tore his ACL, MCL, both his lateral and medial meniscus, and his gracilis tendon (a hamstring tendon).............a non contact injury. With such an injury, although not specifically documented, you can bet his articular cartilage structures took a significant damage hit.
His knee is extremely unlikely to stand up for 17 games, as opposed to the 13 games he spent in college for only 2 years, (let alone into playoffs, if that were to be for his team) to starter numbers trauma especially for multiple seasons. Even as a backup, his days are probably quite numbered from the beginning.
