"I think it was an amazing season," Harbaugh said. "In a lot of ways, beyond description. Incredible"
"I've said so often how proud I was of this team. I thought they played their hearts out," Harbaugh said. "I thought we were a well-coached team. They stand toe-to-toe and fight every time they go out onto the field."
Harbaugh said his only regret about his rookie year in the NFL was how the season ended, in a 20-17 overtime loss to the New York Giants in the NFC title game.
"It didn't have the ending that we wanted," he said. "The football gods had a different ending in mind."
Atlanta's Mike Smith was the last man to win the award in his initial season as an NFL coach, in 2008.
