I think age and success will breed it out of Harper, though I think there will always be a tendency for him to get thrown out and he will always have words with the umpire, even if they are, in the future, gentler.
But right now he's hot and fiery and he's got no laurels to rest on and this team's trying to win. That alone will keep him so riled up he won't be able to take horrible calls in important spots.
He'll never be Mike Trout, but that's why we love him...right?
