He won’t take them. Harbaugh isn’t going anywhere anytime soon. I don’t care if he’s offered a trillion dollars, a starship and a Cuban cigar. Harbaugh. Is. Not. Leaving.That won’t stop teams from trying.Harbaugh going back to the NFL isn’t that inconceivable. He’s a competitive freak and probably wants to win a Super Bowl at some point.Any time soon, though, and the answer is no.
