It's officially December football time as teams are doing everything they can to reach the postseason. With how unpredictable games are from week-to-week, betting on over-under point totals can be tricky. Sit back and let us do the research for you as we determine the best over-under bets for Week 14.

*Odds subject to change

Kansas City Chiefs vs. Los Angeles Chargers UNDER 43 total points (-110) – Caesars Sportsbook

Both offenses are capable of putting up a lot of points, but the Chargers are usually pretty conservative and the Chiefs are too inconsistent. Los Angeles' offense revolves around the running game and timely play-action shots.

Kansas City moves the ball well, but has badly struggled to cash in for touchdowns in the redzone. These teams combined for just 27 points in their Week 4 matchup, so I'll bet the under.

Arizona Cardinals vs. Seattle Seahawks OVER 44 total points (-112) – DraftKings

Both offenses have been a bit hot or cold this season, but there are playmakers galore in this game. Their matchup from a couple of weeks ago was a low-scoring affair, but I think adjustments will be made. Playing indoors should make a difference as well, and with first place in the NFC West on the line, I think both offenses will be sharp.

Pittsburgh Steelers vs. Cleveland Browns OVER 43.5 total points (-110) – bet365

The Steelers have a lot of momentum offensively after scoring 44 points against the Cincinnati Bengals last week, and now faces a Browns defense that ranks 26th in points surrendered and 24th in total yards. On the flip side, the Steelers' defense has been just average against the pass, and Cleveland's offense has been pretty explosive as of late.
