Justin Herbert hasn't won a playoff game in his five seasons under center for the LA Chargers. This is a well-documented talking point, with many skeptics arguing that Herbert needs a playoff win to enter the upper tier of NFL QBs.
While it's fair to criticize a quarterback for a lack of playoff success, Herbert's 0-2 record in the playoffs does not tell the entire story. And quite frankly, the other winless quarterbacks he is grouped with are all on a tier below.
Herbert obviously leads the way, but what about the rest of the list?
