A recent factoid in USA Today correlated the number of playoff seasons different teams had with the number of Quarterbacks who have started for the team since 1995. (The year Brett Favre, assumed the QB job in Green Bay, a benchmark for the league) The list didn't include the Lions, but I will reproduce USA Today's lists with the Lions added as a point of comparison. Another point of interest is the fact that a lot of the same names appear for different teams and many have done time with the Lions.
