They say that if you hear a lie told often enough with the proper conviction, you will eventually start to believe it. We see this play out in politics and pop culture with regularity. Anybody with the motivation to convince people of something being true or untrue that is to their benefit is liable to engage in this behavior.
I happen to think that there are a number of popular beliefs that we hold about the running back position that are either untrue or at least misleading. One of them is that elite running backs don’t win championships, and thus they are not as important as other positions and should be paid less.
