The odds for the Seahawks went up throughout the week, but are coming down a bit now and I placed a bet on them ML @1.60 (as well). The 4 main reasons:
1) The SEA defense has improved so much over the course of the season, they have just allowed 14pts on average in the last games. It wasn't some high powered offenses, but they still found some groove and momentum.
2) I guess Goff will start, but he can't be at 100% with his thumb. The market just seems to wait for the announcement of Goff starting to pound the Rams, but I don't think this is smart.
3) The Seahawks are super healthy just at the right time:

The Rams had an average 4-4 away record this season.
Redskins +8.5, should only be 6.5?
It looks like Heinicke might (have to) start, since Smith is still dealing with this calf injury. Even if Smith starts, it's not safe to assume he will go all 4 quarters, so I wouldn't recommend to put any bet on WFT. Defensively they should be fine, but you can't shut down TB completely, so you need at least a few points to cover the HC, let alone win this thing.
