jay: right

Jay Harbaugh is 25, and therefore there's nothing I can tell you about him that has anything to do with anything. He is Jim Harbaugh's son, he went to Oregon State and then GAed under Mike Riley, he spent the past three years with the Ravens working as a quality control coach, and he knows modern rappists.

This is good, because every coaching staff needs someone who can decipher recruits' twitter.

JIM: This kid says he's throwing "hunnids." Is that some sort of exercise?
JAY: …in a sense.
JIM: Working on his arm, then?
JAY: If so he got that workout from Pac-Man Jones.
JIM: Ah.
JAY: Yep.
JIM: So no.
JAY: Nope.
JIM: Moving on… this kid says he's named "Reagan." Any chance that's code for street drugs?
JAY: No. Pretty sure that's the president.
JIM: /issues offer

This extremely young staff might not need translation skills as badly as Hoke's needed Roy Manning ("ROY! COME HERE AND FIX MY AOL!"), but never hurts. After what looked like an NFL-enforced period of dormancy, JayBaugh has resumed twittering and has done so competently.

If this coaching profile seems heavy on references to twitter, please reference the bit above about Harbaugh getting carded when he tries to buy juice.

Anyway. Here is what Harbaugh did with the Ravens:

For the Ravens, Jay Harbaugh provided statistical analysis, self-scouting reports and breakdowns of opposing defenses.

He did shoot down an opportunity to join the 49ers last year, causing a reporter to write an article with the dubious premise that working for his uncle instead of his dad was a radically independent path:

Beyond Grandpa Jack Harbaugh and the brothers, there is Jay, a 24-year-old offensive assistant for the Ravens so determined to carve his own path in the industry that he turned down a chance to join his father for the inaugural season of Levi's Stadium.

But in that article we do get quotes about Jay. Mike Riley:

"Jay has forged his own way in this business to be a very good young coach," said Oregon State's Mike Riley, who was Jim's head coach for two years with the San Diego Chargers. "Jay is a grinder. He's like Jim to a T."

And the elder Harbaugh:

"One time, I asked, 'Do guys give you a hard time about working for your uncle, automatically look at that as the reason you got the job?' His response was: 'It's my responsibility to not give them the opportunity to confirm that suspicion.'"

That is accurate, and will remain accurate as long as he's at Michigan. That's just life. That is the exact right attitude to bring to the job.

He seems off to a good start in the proving-your-worth department, as he's been prominent on the recruiting trail already. But, yeah, your guess is as good as mine.

"ROY! Did you delete my BonziBuddy again?"
"Yes sir."
"Who do you think is going to call plays this weekend?"
"Sir?"
"…"
"BonziBuddy is not Al Borges on your computer."
"He might be."
"That is an excellent point."

RECRUITING

Promising.

PREDICTION BASED ON FLIMSY EVIDENCE

You got me. Jim Harbaugh is a terrific coach with a great track record of hiring. Jack Harbaugh has literally sired a coaching tree without peer. There are reasons to think this is a good idea and not JayPa redux.

If JayBaugh ends up ascending to the offensive coordinator job without going elsewhere and proving his chops I would be worried. Until then he's just an exceptionally young and motivated position coach whose main job is recruiting. That's a luxury Jim Harbaugh has since he's part OC and full time QB coach of his own team. Also he is Jim Harbaugh.
