Quarterbacks are one of the toughest but most vital positions in all of football. They act as a leader on the field, and if they are good at their job, they end up being the face of the franchise. 

Every team has gone through the ups and downs of finding a franchise quarterback, even those who seem to have it all figured out. The hunt for a successful quarterback is a mixed bag. 

Some QBs are wildly successful and transform an ordinary team into a championship-caliber one. Others end up being disgraceful, acting as franchise killers. 

People always talk about the QBs that rise to success, but how about those that don’t? With that in mind, here is a list of the worst quarterbacks of all time for every NFL team.
