Actually, they are the 5th lightest challenged in the regular season in the history of 1st seeds since the bye week novelty.
If you take every 1st seed of the AFC & NFC since the bye week was introduced (and therefore, the WC round: 1978), and analyze
the records of the teams they beat in the regular season, the 2012 Denver Broncos' opponents have the 5th worst combined W-L %. Here are the top 10 worst and their subsequent result in the postseason:
SBC - SB Champion
SBR - SB Runner-up
CC - Lost in the Conference Championship
DIV - Lost in the Divisional Round

In case you wonder, 2012 Falcons are 14th in the list of lightest challenged 1st seeds. The opponents' record of both teams combined (DEN & ATL) is 0.39904, the 2nd worst in history for 1st seeds (1999, .32639).
Other NE 1st seeds:
2007 NE - 0.46875, 16th toughest
2011 NE - 0.42308, 19th easiest
NOTES
- As noted before, the W-L% shown is from the teams they beat, not from the entire schedule. If DEN would have beaten ATL/HOU/NE, we wouldn't have this discussion.
- This is a list based on strength of victory. Just like most of the websites (PFF, PFR, etc), when a team beats a certain opponent 2+ times, you MUST count their record the same amount of times. 1999 STL beat the 5-11 ATL twice, so it would be 10-22, rather than just 5-11.
