The falcons were founded in 1966 and have never won a Super Bowl. While the Cardinals, Lions, Titans, Chargers, Browns, Bills and Vikings are older and have never won a Super Bowl, all won at least one AFL or NFL title before the 1970 AFL-NFL merger.
For anyone who hasn’t seen it, secret base did a deep-dive series on the falcons. Legitimately one of the most entertaining things I’ve ever watched.

This series is really great! I love secret base.
The Secret Base 7 part Vikings series was incredible too.
