We saw three teams clinch divisions in the AFC during Week 15 with New England capturing the East, Indianapolis winning the South and Denver topping the West.

The AFC North is still open with Cincinnati, Pittsburgh and Baltimore in the running for division supremacy and each team winning this week. If Cincinnati, Pittsburgh and Baltimore all win and San Diego loses at San Francisco, then the three AFC North teams will grab the final three AFC playoff spots.  On the NFC side, if Philadelphia loses, Dallas wins or ties, New Orleans wins and Carolina loses, then we have all six playoff spots locked up in that conference as well.

Some overall playoff notes:

Four teams have qualified for the playoffs through 15 weeks (NE, IND, DEN, ARI), which is the second-fewest teams to gain a playoff berth at this point since the playoff field expanded to 12 teams in 1990 (three teams locked up spots through 15 weeks in 1995).   Also, if ARI, DAL, DET and NO do not clinch their divisions in Week 16, it will be the second straight year that all four division titles in the NFC will go down to Week 17.  That's never happened in back-to-back seasons in a conference going back to 1970.  In fact, only five times have all divisions in the AFC or NFC come down to the final weekend (1980 AFC, 1983 NFC, 1987 AFC, 2000 AFC, 2013 NFC).
