Why Drew Brees never won MVP

Another doozy I never quite understood is the whole time Marino held the passing title it was called 'the holy grail' of all sports bc NFL QB was considered the 'toughest, most cerebral position in all of pro sports'....then Drew beats it repeatedly then it's ho-hum...Drew was a unicorn, should have been more like KC, a dynasty
At the time, Marino was the only one to get to that threshold.
In Bree’s’ era, you had Drew, Favre, Brady, Big Ben, and Eli hovering around there.
