PITTSBURGH — Pittsburgh Steelers defensive players know some things are predictable about Dick LeBeau, their 71-year-old coordinator: the push-ups he does before practice, his annual recitation of The Night Before Christmas and his greeting at their daily morning meeting. "The first thing he says to us is, 'Good morning, men, it's a great day to be alive,' " Steelers defensive end Brett Keisel says. "He's just young at heart, and we all feed off of it."
