The 2012 NFL regular season is in the books and the playoff fields in both the NFC and AFC are set. Brad Wells of SB Nation takes a look at the field in the AFC following Week 17 action. The most notable development, of course, was the Indianapolis Colts knocking the Houston Texans off the No. 1 seed with their convincing home win. The loss sends Houston to the three hole thanks to Denver capitalizing and earning the No. 1 seed following their drubbing of Kansas City. Watch for more analysis about today's action and next weekend's Wild Card matchups.
