They grew up as sons of a football coach, and they're now in an elite place every football coach aspires to be. "Enthusiasm unknown to mankind" was one of Jack Harbaugh's favorite sayings while they were growing up, and they've now got some sayings of their own.
The brother thing fits into it so well, in fact, that Jim paraphrased Shakespeare twice when talking about it.
"That's my brother on the other side," he said. "I love him and care about him very much. But they're also my brothers on the sidelines for he who sheds his blood today shall be my brother."

"We both desperately want to win," Jim said. "But we understand the other side of that."
