After 18 years, Ravens HC John Harbaugh was fired by Baltimore on Tuesday. While the move didn't come as a surprise after the Ravens' season-ending loss to the Steelers, it sent shock waves throughout the rest of the league.
Teams that once had other ideas to fill their head coaching vacancies now know Harbaugh is available. And teams that don't even have head coaching jobs technically open yet may want to hire him.
It's notable from a Chargers' standpoint for a few reasons. Obviously, Chargers HC Jim Harbaugh on a human level will likely feel a certain way about his brother getting fired.
