13. Boomer Esiason (underrated)
Boomer Esiason is like so many men on this list, great but just not the best of his generation so history forgets about their greatness. Case in point: Esiason led the otherwise inept Bengals franchise to a Super Bowl in 1988. Who did they come up against? Joe Montana and the San Francisco 49ers.
However, Esiason ranks 16th all-time in both passing yards and touchdowns so the guy has the numbers to prove his credentials. What’s more, Esiason has a higher career passer rating than John Elway and Johnny Unitas. Impressive.
