I am certainly not trying to compare the organizations. Really not much of a comparison.
Chargers aren’t WFT Cleveland Brown level bad, but they certainly aren’t a top NFL organization.
Pittsburgh is.
No doubt. In San Diego, Rivers played for 4 different coaches in his16 years with the Chargers.
In Pittsburgh, Roethlisberger has had 2 head coaches for his entire career and has had the same head coach since 2007.
