I'm probably in the minority here but I would never sign a RB to a high dollar contract unless he was a generational RB.
I would draft the best ones, work horse them, and let them go, rinse repeat.
Unfortunately for that position, I think most NFL teams should carry a stable of 2 RBs, 1 bruiser, 1 nimble, and game plan around using them equally. Never committing to 1, keep defenses guessing. When you have 1 type, it's easier to game plan against, unless you have a dominant offensive line.
I see the future NFL doing the same with QBs. But it's not caught on yet. The market doesn't support it. But imagine you have a aaron rodgers and Lamar Jackson, they are both okay with being dual QBs at lesser pay. You switch them out constantly through the game. How do you game plan for that?
