Jim Irsay, the Colts' owner, asked Arians to take over once doctors diagnosed Pagano with cancer. Arians agreed, with one stipulation: that the Colts leave on the light in Pagano's office until the coach returned.
"Christmas Eve, we had our normal game-plan meetings and I was walking out of the building and all of a sudden I looked and the light was off," Arians recalled. "I had to get in the car and dry up some tears before I could drive home. It was an extremely emotional night -- the best Christmas I've ever had."
