The coach of the New York Jet’s football team, Rex Ryan, was in Manhattan today promoting his book “Play It Like You Mean It.”

Ryan is known to sports fans for having guaranteed a Superbowl win last season only to fall short.

The question of does he regret the “guarantee” is answered in the book, when he sneers at coaches who try to “downplay expectations” — saying “to hell with that,” and then adding “we’re going to kick their ass.”

Throughout history, pride (hubris) has been understood to be a bad thing — sure to produce bad outcomes over time. Today, it’s rare to find leaders who understand the power and truth of humility.
