Yup.
The position has been devalued overall, with the league being so pass heavy a RB's best trait may actually be their receiving abilities as opposed to just being a pure workhouse style back, Derrick Henry being the exception.
With RB being such an easy position to replace it makes no sense to break the bank on a RB, especially with most of the highest paid RB's usually having a down year almost always after they get paid top dollar. Zeek Elliot had a good season & was still in the top 5 in rushing after he got paid but his YPC went down & yards overall went down, not necessarily all his fault though.
But Gurley & LeVeon Bell complelty fell off the map after getting the big contract, I'm always happy when guys get the money they deserve so it's no slight on them, but if I'm a GM of a team unless I got a surefire HOF'er I'm just drafting a RB in rounds 2-5 anytime I need a RB, that money goes to a more valuable spot like CB, OT or Pass rusher.
The 49ers were a team that made it to the SB running it down people's throat with a RB stable of Mostert, Breida & Coleman & none of them broke a 1,000yds. RB by committee is the smart way to go now, you get more bang for your buck & you keep guys healthy with less wear & tear on their legs.
