All true, but..... It just seems that often when backs go through a year like that, after a number of highly productive years, they just lose something, and never again approach what they once were.
GB is going from a 5yds/carry rb to a 4yds/carry rb. Jones never averaged less then 4.6/carry over a season. Jacobs has twice been under 4.0/carry (3.9 in 2020, 3.5 last year).
What I hope is that Jacobs becomes the workhorse, consistent running back that Dillon always teased at being but never really was, and that GB finds a quick, fast and elusive runner and receiver to replace what Jones was, even if for fewer touches per game than Jones was.
GB is only half done rebuilding their backfield.
