Well, his bio may give us some clues...
"Their son's death was not the last tragedy for Rick and Joanne. Both were especially hard-hit by 9/11, as Joanne's brother and Rick's closest friend, Billy Minardi, was working as a bond trader for Cantor Fitzgerald on the 105th floor of the north tower of the World Trade Center when it was struck by American Airlines Flight 11. Since 2002, UofL has designated a December home game as the Billy Minardi Classic, and the university named a dorm on campus as "Billy Minardi Hall". Only a few months earlier, another brother-in-law of Rick, Don Vogt, was killed after being hit by a New York City cab."
Clearly his experiences left him rudderless. It takes a good pastor to get a man through stuff like this.
There is a guy that runs this fan forum for the college football team I follow who received a frantic call from his wife that their 16 year son had just gotten killed in an auto accident. While she was speaking with him on the cell while she was driving a car ran a red light, hit her and killed her.
Life can be very cruel.
