NFL Week 12 is a little short on marquee matchups, but there is still plenty of betting intrigue.

Of all the games on the slate, the Indianapolis Colts vs. Kansas City Chiefs clash is the most interesting. Kansas City was -4.5 on the look-ahead line, but reopened at -3.5 after losing in Denver on Sunday.

The Los Angeles Rams host the Tampa Bay Buccaneers as 6.5-point favorites. Both teams are coming off tough games, with the Rams narrowly beating the Seahawks (despite Sam Darnold's four interceptions) and the Bucs just couldn't overcome the Buffalo Bills. This is still a bout between contenders worth keeping an eye on.

Here's a full look at the NFL Week 12 opening odds and early line moves, starting with Buffalo vs. Houston on Thursday Night Football.
