The Top 20 Quarterback Seasons of the 1970s.

The quarterbacks are ranked by their rating compared to the rest of the league; 100 is average, 115 or so is Pro Bowl Level and above 130 is an all-time great season.  QB Rating not the perfect measure of a quarterback, but it is probably the best available.  Roger Staubach is well represented on the list, and all of my older friends and uncles tell me he was the best QB in the ’70s.
