Bookies won't bring things down rapidly in cases like this, there's money to be made on emotion and they know it. A key measurable metric they all factor in when coming up with markets. Dangle a $31 carrot out there at a point like this, and they'll take in far more $ than if they bring it right in straight after a big win. Of course there is risk to them, but that's their business and they know it inside out.
Beat the broncos and those odds will then drop moreso than they would after a game like last night.
