I took the bait. I never think of huge lines as "traps" when the teams are NE, PIT, Dallas, GB etc... they are literally the most popular teams in the league and they always get bet on heavily (though the G-men are popular too, obviously).
This week, when I guessed the lines, I had Pitt as a 4 point fav. I also had Det as getting maybe 3 points and Houston getting maybe 4.
On those games I was way off. So, at the end of the day it will be interesting to see how these 3 games go. If Pit, NO and GB covers than maybe these were trap games. If they don't, maybe the books either hung a bad line, or the public just can't resist betting on stars like Brown, Big Ben, Brees etc...
