Our updated Week 18 fantasy football Flex rankings (RB, WR, TE) for 2021. Follow these fantasy football FLEX ranks when setting your Week 18 lineups.
Welcome RotoBallers to Week 18 of the NFL and fantasy football seasons. Below you can find our team's updated fantasy football Flex rankings for Week 18. For anyone who's league is still going, or playing some DFS, let's take a look at where FLEX options like AJ Dillon, Darnell Mooney, A.J Green, Cedrick Wilson and Amon-Ra St. Brown rank, among others.
In addition to our staff rankings, below you will also find a summary of the important fantasy football injury news for this week. There are many key injuries and COVID-19 situations to keep track of, so be sure to check back until kickoff. 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!
A big congrats to our very own Nick Mariano who once again finished as a top-10 ranker in 2021 across the entire fantasy football industry!
