First off, kudos to Vikings QB Kirk Cousins for his work ethic and also his willingness to do what would make a lot of us cringe: Go back and look at mistakes he made as a younger professional in an attempt to unpack how he became the player he is now.
I, for one, would not have the stomach to read everything I have ever written — first and foremost a novel completed about 20 years ago that I am terrified to (likely) discover is not just unpublished but unpublishable.
But Cousins has made this sort of self-assessment the centerpiece of his career.
