Welcome back RotoBallers. In this article you'll find our updated fantasy football Flex rankings for Week 15. In a crucial week that will determine many fantasy playoff births, where do Christian Kirk, Jordan Howard, Brandon Aiyuk, K.J Osborn and Michael Carter rank, among others?
There are no more teams on bye, but make sure you follow the COVID news all weekend long using our updated NFL COVID-19 Tracker for Week 15. Three games have already been rescheduled by the NFL, and we will continue to update our rankings as any new updates come in so check back often.
Our updated FLEX fantasy football rankings are built out weekly by three of our lead fantasy football analysts - Nick Mariano, Pierre Camus and Brandon Murchison. These fantasy football Flex rankings are geared towards the skill positions that are played in traditional Flex spots (RB/WR or RB/WR/TE). For most fantasy leagues, that Flex spot consists of running backs, wide receivers and in many cases tight ends. Make sure to follow the injury updates below, and good luck RotoBallers!
