Every NFL team's record vs. the spread and Week 12 early lines

The margins are so thin in this league, which is why we see so many weekly spreads that are tight (less than seven points). It's not that the sportsbooks are afraid of taking a side -- it is that we are truly talking a game of inches. It is exactly that train of thought that makes underdogs in such spots an increasingly profitable venture.

From 2013-17, these small dogs covered at a 49.8% clip and won outright 37.5% of the time. Those aren't bad numbers, but the cover rate is a net loss and the outright number needs to flirt with +170 for a projected profit over time. Again, not bad, but nothing really to follow. In the four-plus years since, however, the cover rate has spiked to 55% and the outright win rate to 42%. That cover percentage very much clears the 52.4% number that it takes to be a profitable bettor, and the outright number requires only +138 number on the moneyline to draw interest. You'll notice there are more than a small underdogs on the Week 12 slate with a moneyline price tag north of +138. Consider me interested.

Saints ATS: 4-7

Chiefs ATS: 4-6
O/U: 5-5
