Super Bowl LII was, in a way, an illustration of how NFL teams approach their backfield: The Philadelphia Eagles and New England Patriots each relied upon a trio of running backs in that game, something that was consistent with how they operated during much of the 2017 NFL season. It's a tall order to lean heavily on a solo back in today's game, as finding a player who has the skill set to play in any role and combining that with the durability required to take on the physical toll for close to 70 snaps a game is difficult.
For fantasy football purposes, there is no greater roster asset than one of the aforementioned select backs who can dominate snaps and touches for his team: Le'Veon Bell, Todd Gurley II, David Johnson and Ezekiel Elliott -- those types of players. You have one of those players, you start him.
But let's sort through some less obvious backfield situations -- those that include a host of backs who all could contribute. It's early, and much of how these players will be utilized will be determined and earned by how they perform in training camp. Consider this our too-early look at crowded backfields with an estimation of who we believe carries the most value.
