JOE MONTANA is the best Quarterback in NFL history. _____________________________________ It depends on your definition of "greatest". If anyone answers this question with one quarterback, they are WRONG. There are too many factors that go into this answer.
Tony Romo, not only sucks, but is obviously not the best. Peyton Manning of the Colts is by far the best quarterback in NFL history.
