Never been to the SB? Heck, has he ever made it past the 2nd round of the playoffs?
But good point. The only thing that worries me is that, outside of Levy who never won the SB as Bills HC, Shanahan and Belichick won SB's as coordinators. From what I've seen, Jauron has not only NOT won a SB as a coordinator, his defenses outside of 1 year, weren't all that good.
