What happened: Over 34 years ago, the Atlanta Falcons traded second-round quarterback Brett Favre to the Green Bay Packers for a first-round pick in the 1992 NFL Draft. Atlanta eventually used the 19th overall selection on running back Tony Smith, while Favre headed north to become a franchise icon.

Why it matters: The transaction launched a dynasty in Green Bay, where Favre won three consecutive MVPs and a Super Bowl title. Conversely, Smith played only three seasons in Atlanta, recording 329 rushing yards as the Falcons' return for a future Hall of Famer.

What to watch: Front offices continue to cite the Favre deal as a masterclass in scouting persistence and a warning against giving up on young talent prematurely.
