Why don't teams draft and develop pass catching running backs
In the passing age it seems like pass catching running backs are becoming more and more important in the offense
And they seem to be really important to winning. The 49ers dynasty always had a few guys to catch the ball out of the backfield and the Patriots dynasty had no shortage of them
They're good for 600-1000 scrimmage yards a year and help spread the ball around
So why don't teams put more resources into them, it seems like most of them are some rando castoffs or rookie free agents or late round draft picks
