RB9 finished in week five and a very inefficient one. So, I'm just not looking forward to seeing what the Saints are going to be able to do against Brian Flores and the Vikings. League best defense pretty much overall and also for our purposes and PPR points for game allowed to running backs.

Kamara faces league-best Vikings defense; inefficient despite RB9 week.

Kamara finished as RB9 in week five but in an inefficient manner. Hartitz is concerned about the Saints' matchup against Brian Flores' Vikings defense, which is league-best overall and allows the fewest PPR points per game to running backs. The Vikings' blitz-heavy scheme may force more CJ Donaldson into the game. Kamara was also banged up last week, making him a mid-tier option despite one solid game.
