Here's a fact I never knew, posted from the New York Times in 1976 heading into Week 5:
Willie Lanier is playing outside linebacker, with the rookie, Jimbo Elrod, in the middle.

So the Chiefs gave Jimbo the middle linebacker job and put Willie on the outside. I'm surprised by that move. But then Willie killed the usurper to his throne and apparently moved back to the middle.
