What does he mean?

Is he promising that he'll play better? Prepare better? React better?

Goff has never had a problem with saying the right thing. He's been coached on that his whole life. Maybe his quote is a great sign of leadership but my first response was why didn't you do what you needed to THIS time? He seems to imply there was more that he could have done or something he could have done differently. If so, it's very disappointing.
