10. Steve Young
This two-time NFL MVP (1992 and 1994) was the San Francisco 49ers’ anointed successor to Joe Montana, and was actually more physically gifted and talented than Montana. The main knock on Young is that he only managed to appear in and win a single Super Bowl (XXIX), three less than his predecessor.
Young is the rare left-hander to make this legendary list, and he was also unique in that he was an extremely deft scrambler, but combined that with an ability to stand strong in the pocket and deliver the ball to receivers like Jerry Rice with great touch and deadly accuracy. Most “running quarterbacks” do so due to lack of height or a strong enough arm, but Young had it all.
