See what the guaranteed money is.
So far all of the veteran RBs have been at a 7 figures Average. I don't think you'd see anyone landing 8 figure average for that position.
Even the likes of Barkley and Jacobs if they didn't get tagged, hard to envision they would have a lot of interest from teams looking to hand them $40 mill guaranteed that CMC, Cook, Kamara, Zeeke got a few years ago.
