49ers vs. Rams, Thursday Night Football: Odds narrow

The San Francisco 49ers are fighting through a hangover, trying to wake up, put their pants on and stumble into work after a dream season that had them narrowly missing a world championship. Despite their recent struggles, the 49ers are favored over the St. Louis Rams this week by three points. But there's something notable in the line's movement this week.

The 49ers opened the week at 3 1/2-point favorites over the Rams in St. Louis. Since then, the gap's closed just a little, down to three points in favor of the visiting team.

Why? For one, there's the Aldon Smith news. It wasn't known until after last Sunday's game that he would out this week (and indefinitely beyond that). There's also a question about whether or not Patrick Willis will play this week. Along with the injuries go this team's recent struggles, something the Rams can relate to, and the recent history, i.e. 2012, between both teams. Both of which make for a tough gambling prediction.

The spread isn't the only line that's moved. The over/under opened at 44 points. It sits at 41 1/2 now, reflecting the offensive struggles both teams have had to deal with this season.

If you are thinking about wagering on this one, I'd stay as far away as possible. The 49ers are 7-2-1 over their last 10 games against the Rams, but St. Louis tied them and beat them once last season. It's hard to tell right now, but this is mostly the same Rams defense that kept the 49ers in check last year.
