The NFL has officially hit December as playoff races are heating up around the league. In what was one of the wildest weeks in recent memory, 12 games were decided by seven-or-fewer points -- tied for the most in a single week in NFL history.

If the Baltimore Ravens want to be taken seriously as Super Bowl contenders, they’ll have to start playing some defense first. Until then, bettors clearly don’t trust them against other contenders.

We saw likely playoff teams in the Chiefs (two points), Texans (three) and Vikings (one point) win narrowly as favorites again. Do you consider tight wins against shaky (or worse) opponents a cause for concern, or something to be encouraged by going into the postseason?
