Arguably the biggest matchup of NFL Week 9 is the battle between the two best teams in the NFC -- the New Orleans Saints and the Los Angeles Rams. The Rams sit at 8-0 while the Saints are right behind them at 6-1. If Los Angeles can win Sunday, they'll have a stranglehold on the No. 1 seed in the NFC.

After the line opened with the Saints as 2-point favorites at home in the Mercedes-Benz Superdome, the line has swung three points favoring the Rams by a point now.

Lines move all the time, but three points of movement to flip flop the favorite means there has been a lot of action -- mostly on the Rams.

For reference, the Saints are 5-2 against the spread this year, but have yet to be a home underdog. The Rams are 4-4 against the spread and are 2-2 as a road favorite. New Orleans is 4-1 when facing an NFC opponent against the spread while the Rams are 2-3. So while there's a lot of confidence in the Rams overall, recent history says something different.

Since the line moved as drastically as it has, there's a real chance to win a bet on the Saints and one on the Rams, if the game ends up being as tight a contest as it's expected to be. Either way, it's sure to be a great game on Sunday afternoon.
