[The Goat]

I remember when G Williams left DC he said something like you never know what can happen down the road and he might be back. His defense won that SB as much as Payton/Brees offense. Hard to find that kind of experience IMO. Is there another candidate who's been part of a SB winning team?

And it doesn't require an offensive HC to maximize RG's potential. Belichick is a defensive guru, and I'd say his mentors hip of Brady has been pretty solid. Another similarity between belichick and Williams, both were very underwhelming in their first HC experiences.
