Entering Week 5 of the 2018 NFL season, only the Rams and Chiefs remain as undefeated teams. But in terms of playoff chances, at this point, only one can be considered a lock for the postseason.
The Cardinals, on the other hand, are the league's only winless team. Based on their playoff chances, they probably should start planning for next season.
