In daily fantasy football, like in most things, getting the fundamentals down is integral toward laying a foundation of knowledge to build from as you progress as a player. For DFS, that means learning the best strategy for your flex position.
In DraftKings classic games, the flex position can be filled by a running back, wide receiver or tight end.
In cash games, the flex position should likely be a running back. They have the most consistent production of the three positions available. Of course, not all players are equal, as there are consistent receivers and inconsistent running backs and much will depend on matchups and available players.
Don’t play a running back in the flex spot just to play one, but on average, they are going to be safer. The safest backs are three-down backs who get good work in the passing game. If you can’t get a back with that kind of profile into your flex spot, then looking at receivers who see a lot of targets is your next best option.
In tournaments, you want to lean in the other direction by rostering a wide receiver or tight end in your flex spot. Again, this isn’t a hard and fast rule, but on average, tight ends and wide receivers are found in the flex spot of GPP winners. They are more volatile, so they are a bit cheaper and when they hit, they give you similar upside to running backs. Again, what kind of receiver you use is important, as big play receivers are more valuable in GPPs than possession receivers.
