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 2015. It appears that the 49ers will hire an "OC" to pair with defensive line-turned-head coach Jim Tomsula.

As Tomsula rounds out his coaching staff with an offensive play-caller, let's take a look back at who's held this responsibility since Walsh stepped down in '89.
