Video: The Perfect Zero RB Team Is Out There (Best Ball)
Charbonnet honestly could be a quite good late season hammer for zero running back teams. The issue with taking someone like that on a team that has no projectable running back scoring is there's going to be some weeks that Isaiah Pacheco's 7.6 points are going to count for us... Charbonnet actually is kind of fool's gold for this specific team.

Fool's gold for zero RB teams; too much volatility without projectable RB scoring.

Charbonnet is identified as 'fool's gold' for zero running back teams despite being a potential late-season hammer. Davis Mattek explicitly avoids selecting him because on a team with no projectable running back scoring, the unpredictable weekly contributions from backup running backs would create too much volatility and risk. The issue is that weeks with Isaiah Pacheco's 7.6 points or Dylan Sampson catching four passes from Deshaun Watson for the Cleveland Browns could land in a zero RB team's starting lineup, creating problematic variance.
