The Atlanta Falcons sure aren't what they used to be. They have a five-game losing streak and a a point differential of minus-80. Their offense has also been sputtering in that span, failing to score more than 13 points in four of those aforementioned five losses.
Believe it or not, the Bills have been the third-toughest matchup in the NFL for running backs this season. The addition of rookie linebacker Kiko Alonso has really help strengthen their front seven. Plus their defensive line has been solid in allowing there backers to get clean alleys at backs.
S-Jax was expected to be an RB1 in all formats with how often the Falcons were in the red zone last year, but he's currently yielding just the 49th-best value in PPR leagues.
The good news is that he's coming off his best game of the season with a 79-yard, one-score game on his 19 touches. Still, he's a risky play and is more of a flex guy in standards and a low-end RB2.
