In the NFL always look at the result of the road team the prior week. It's a cheap tip off toward what type of intensity level to expect. I've mentioned this often in the 9+ years I've posted on this site. Road teams coming off a loss fare 9% better against the spread than road teams coming off a victory. It's the difference between slight positive expectation and slight negative expectation. With home teams it doesn't matter at all. There is no long term trend based on how the home team fared a week earlier.
New England and Chicago were road teams coming off losses as favorite. That aligns with energy and upside. New Orleans also was in that role. But once you get to road favoritism of that level there are many dangers and additional requirements.
Road teams coming off big home victories are susceptible to flat efforts on the road. That happened to the Dolphins, Seahawks and Lions. The Steelers also showed nothing after winning at home a week earlier. Again, it's a favorable trend but not an absolute. Naturally there can be exceptions, like the Texans who had such an embarrassing season last year they are not yet ready to throw away games on the road, or the Jaguars who simply aren't very good and got thumped on the road despite losing a week earlier.
BTW, it was not a good sign when the bettors took the Bills from +1 to -1.5 in the late going. I'm not sure that move was noted on this site. The late money flooded in on Buffalo, identical to our meeting on the road in the next to last game last season. Those late moves have an erratic history over the past 3 decades. Recently the late money has been getting there. I've been receiving conflicting information on which betting group is responsible and who is doing their handicapping.
I have no idea how anybody can expect an easy victory over the Chiefs, a playoff team now 0-2. Much more often than not a road team in that situation will produce an energized desperate performance. I was rooting for the Chiefs to pull out that game yesterday, helping the Dolphins next week and also removing Denver from the unbeaten ranks.
