In 2010, in his last season at Stanford, Jim Harbaugh famously described how focused he was on football.

“I don’t take vacations,” he said. “I don’t get sick. I don’t observe major holidays. I’m a jackhammer.”

Four years later, in what is certainly his last season with the 49ers, Harbaugh insists he’s retained his jackhammer qualities amid the endless chatter about what his future holds. In a conference call with the Arizona media on Wednesday, Harbaugh maintained he hasn’t been distracted by the talk because he’s so focused on prepping for a largely meaningless regular-season finale on Sunday against the Cardinals.

How can Harbaugh avoid the 24-7 Harbaugh news cycle? Easy, he insisted. No Internet. No TV. No talk radio … these assertions begged the question: Is Harbaugh, who, in truth, has always been well-versed on what beat writers have written about his team, the lone American depriving himself of TV and the Internet?

“Stalwart-like in my focus,” Harbaugh said. “There has to be another American beside myself. Don’t you think? Yeah, I bet there is. I would think there would be plenty of Americans who probably focus on another task at hand, and dedicated to the mission they have, and excelling and not having distraction.”

Yes, Harbaugh is finishing his tenure with another verbal flourish. Here are the highlights of his conference call:

On if this week is a unique week knowing that they are preparing for the last game of the season:

JH: Knowing it’s going to be the last game of the season, yeah, that’s been unique. I guess that’s only happened one other time since we have been here. Yes, it’s unique, but the preparation and the focus is on preparing for the game and winning the game. That’s where the focus and the preparation have been. And, our guys have very possibly enjoyed each other a little more and make sure that staff, coaches, players enjoying it and giving it your very best. That way you can feel good about what you accomplished.

On Russell Wilson having success against the Cardinals last week and if he takes anything away from that regarding Colin Kaepernick for this week:

JH: Russell Wilson has a lot of good games.”

On if Kaepernick might have some of the same success as Wilson:

JH: Colin has had a lot of great games. We understand the task, the challenge, of our offense playing against Arizona’s defense. (They) do a tremendous job. So many players on that side of the ball are just at the highest level and outstanding aggressive scheme. Just have great respect for them. Larry Foote has played every snap of the season; a lot of examples. Our team is understanding the challenge, and that’s what we’re preparing for right now.”

On what he would say cost them a shot at the playoffs this season:

JH: We didn’t win enough games. We were very competitive in just about every ball game and had those opportunities. That’s the National Football League. It’s a great test every game, every season. They do a tremendous job making it a great test.

On what the season has been like for him with so much swirling about his future with the 49ers:

JH: What’s it been like? (Reporter: “Yes.”) The interesting thing is if you don’t look at the Internet and you don’t watch T.V., you really do not know that it’s going on. That has been exactly what I have done. Put the focus on the week of preparation, put the focus on the players and the coaches and what we are trying to get done here. It works if you really don’t pick up … On the way home, you don’t turn on the talk radio and you don’t look at the Internet, you can be completely unaware that anything is swirling. I walk by people and I see their faces. I know something is going on. (laughing)

On him being the one American not watching TV or going on the Internet:

JH: None of it. Not a single bit of it. Stalwart-like in my focus. There has to be another American beside myself. Don’t you think? Yeah, I bet there is. I would think there would be plenty of Americans who probably focus on another task at hand and dedicated to the mission they have and excelling and not having distraction.
