What is flex in fantasy football: Understanding the basics

As the name suggests, a flex spot in fantasy football is a flexible position that allows you to start players at multiple positions. NFL fantasy leagues allow managers to play an extra wide receiver, running back, or tight end as a flex position in the starting lineup. Most leagues, however, don’t allow a quarterback (QB) in this slot, but some leagues do.

Before you can draft a player to your flex position, there are a couple of factors to consider. One is the type of NFL league you are in. For PPR leagues, you want a flex player who will get several receptions, such as a pass-catching running back. If you are in a standard scoring league, touchdowns and yards gained would be the scores to prioritize. In this guide, “What is Fantasy football?” I have discussed how scoring affects the overall draft strategy.

Using flex position in fantasy position: Tips and strategies

Flex position in fantasy football comes with several benefits, but how well you will maximize the flex position depends on the strategy you have in place. Here are a few tips you can borrow to make the most of this feature.

Conduct Thorough Research

A flex player in fantasy football should give you a strategic advantage. Ideally, you want to start a player in the flex spot with the most favorable matchup or who will likely receive the most touches or targets.

Use the Flex Spot for Late-Game Players

Enjoy more flexibility by placing a player with a later game in the flex position. This way, you can adjust your lineup based on new updates and even pivot to another position without affecting the entire lineup.

Adapt Your Strategy Accordingly

The best flex player for your lineup will depend on your goals and current standings. If your lineup has a favorable matchup, you can go for a more consistent player. However, you can opt for a high-upside flex player if you are an underdog.
