This is sort of par for the course with Harbaugh interviews. He avoids pitfalls and soundbites. He doesn’t riff on open-ended questions. He’s not there to “sell himself” through the media. Like Bill Belichick or Gregg Popovich, you need to come with direct, targeted inquiries to pry things out of him. Even then, he will probably stonewall you.
Quick reminder that no one outside the media cares how cooperative coaches/players are with the media.
