It's an awesome responsibility, not only to maintain the level of success the NFL has, but to build on that.

The same mistakes can never be repeated.

I am awake a lot of nights.

It is a privilege for me to serve the NFL. It is the only place I have ever wanted to work.

HGH testing is happening in Olympics. The science is there. It is a valid test.

I don't expect to try to get people to like everything I do. I want them to respect what I do.

When there's a pattern of mistakes, something has got to change.
