Week 13 is here RotoBaller, and we are rapidly approaching the fantasy football playoffs! Welcome back to another edition of our fantasy football Flex rankings for Week 13 of the 2021 NFL season.
For those who aren't familiar, in this article below you will find our Week 13 fantasy football rankings for the Flex spot our put together by three of our lead NFL 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.
In addition to our Week 13 rankings for fantasy football, you will also find a quick rundown of relevant fantasy football injuries to take note of when making your lineup decisions:
