2. Fran Tarkenton (underrated)

Fran Tarkenton was one of the most clutch quarterbacks ever. He was responsible for 34 game-winning drives over his career, which ranks ahead of men like Joe Montana and Tom Brady. Despite this, he is often overlooked when talking about the greatest quarterbacks of all-time.

Throw in his incredible numbers and you’ve got a legitimate top 10 quarterbacks of all time here. Tarkenton ranks 6^th all-time in passing yard and 4^th all-time in passing touchdowns. This was in a day before modern offenses were airing it out on every play.
