ESPN partnered with Pro Football Reference and sorted through 721 quarterbacks who have made their NFL debut since the start of the Super Bowl era (1966-present).
Together, the two sites analyzed these 721 quarterbacks in regard to where they played their final year of high school before going on to the collegiate and eventually NFL ranks.
The findings were interesting. For instance, the state with the “highest rating vs. expectation”, which takes into account state population and number of Divison 1 programs in the state, is Louisiana. Louisiana has produced 25 NFL quarterbacks who have gone on to win a combined nine Super Bowls.
