Steve Kerr cited Kobe Bryant and Michael Jordan, two of the most "clutch" performers of all time, as examples of players who want desperately to make the important shot, but are tough enough to accept the outcome, positive or negative. "That's really the key. You have to be willing to live with the result. You have to be tough enough to live with the results."
Accepting the consequences doesn't mean that failing doesn't bring hurt or disappointment. It means that you have the courage to accept the result without fear affecting your ability to perform and that you are also willing to get up off the deck and try again.
