Rome wasn't built in a day, and the difficult situation of running backs in the League also wasn't caused overnight, but rather by various contributing factors.
Firstly, after top running backs deliver a top-season performance, securing a lucrative contract becomes increasingly challenging.
Teams worry that running backs can't sustain top performances and also believe their contribution to the offense is limited. Therefore, while quarterbacks, wide receivers, and offensive line players keep landing record-breaking contracts, star running backs are often left "begging for crumbs."
It's hard to renew contracts, especially long-term or high-value ones.
Secondly, the draft prospects for rookie running backs are getting worse.
