Kurtenbach: The 49ers lucked out in landing Raheem Morris as defensive coordinator

They say it’s sometimes better to be lucky than good.

That’s nonsense. It is always better to be lucky than good.

And on Sunday, Kyle Shanahan and John Lynch got lucky. Again.

Raheem Morris is coming back to the Bay to be Shanahan’s defensive coordinator. It is a home-run hire, one that provides an immediate upgrade to the 49ers’ coaching staff and, perhaps more importantly, might finally jam up the revolving door at the DC position.

Morris is the fifth defensive coordinator in Santa Clara in five years.
