what is flex fantasy football

In fantasy football, the Flex position is an extra roster spot in the starting lineup that allows for more variance in how fantasy managers build their rosters. It is a position that accepts various positions depending on the leagues rules, most commonly including running backs, wide receivers, and tight ends. The purpose of the Flex position is to allow more flexibility in starting players at multiple positions, which increases the skill of roster construction and creates more diverse rosters. The best fantasy Flex players are usually at running back or wide receiver, and the position can be altered heavily throughout the season to find the player with the best matchup. Different types of Flexes include the standard Flex, which allows fantasy managers to start a running back, wide receiver, or tight end, and the Superflex, which allows you to also start a quarterback.
