1.
The act of backing ones-self in a competitive situation, with the confidence that you will succeed - i.e. there is no such thing as a 50/50 ball. It's always yours.
I really admire Jonny Wilkinson's backage in the contact, he really backs himself to tackle anyone that comes near him.

or alternatively;

Newcastle backed themselves to bounce back and score after the break, having fallen behind in the first half.
