Did you know that Bill Walsh never hired an offensive coordinator?
That's right, from 1979 to 1988, the San Francisco 49ers head coach assumed both roles.
Flash forward to 2016 and new leading man Chip Kelly has tabbed Curtis Modkins to be his second-in-command on offense.
As Modkins begins work as the 49ers offensive coordinator, let's take a look back at who else has held this responsibility since Walsh stepped down in '89.
