D00d, Norm Evans.

He went to the Pro Bowl twice: one time after the Dolphins' undefeated '72 season and then again after the '74 season. He was with the Dolphins in three Super Bowls in a row (VI, VII, VIII), and they won the last two of those.
Evans is now 81 and was an offensive lineman in the NFL in the '60s and '70s, so there's approximately zero chance he's even lucid at this point, so obvz not a head-coaching candidate.
I just wanted to mention him because the Dolphins didn't protect him in the expansion draft, so he ended up going to the
Seahawks, playing in 36 games for them (starting 25), and he founded the
Seahawk Report, which ended up being really important for me growing up in Maine as a Seahawks fan who didn't know any other Seahawks fans. My parents wrote to the Seahawks and asked if there was any kind of Seahawks periodical to which they could subscribe for me, and the Seahawks wrote back and told them about the
Seahawk Report, so I had a subscription. I'm pretty confident it was the only one in Maine.
