Say we win the division -will Saints be the biggest home playoff dog in NFL history?

It would take something major like Carr and Winston both getting injured in week 18 of a Saints division-clinching victory, and Hill or Haener having to start at QB in the playoff game....for the Saints to be a 10 or more point underdog at home.
I think the Saints would gain a point or two with Hill vs Carr. The entire world can see what only Allen can't.
