This will be a very tough game... I don't buy the 7 pt spread.
Detroit has handled us without too much trouble the last 2 times we've played them - granted one of those games was without Rodgers, and both were in Detroit; but still, Detriot can be a very tough out, and they have a lot of weapons.
They'll likely contain our offense under 30 pts, so it all depends on dunderdummy - of course. Almost every game comes down to dunderdummy.
