One of the strong principles that I believe in is that you're always learning, whether you're a commissioner, a current general manager, a president or an owner, or somebody that's trying to become a general manger or a coach in the NFL.
Change before you're forced to change.
When there's a pattern of mistakes, something has got to change.
The same mistakes can never be repeated.
My goal was to prove to my family I wasn't a dummy.
My job is to protect the integrity of the NFL and to make sure the game is as safe as possible.
