Harbaugh’s quirky personality and clash with management in San Francisco are reportedly a concern, but they may be willing to move ahead with Harbaugh if their concerns are alleviated.
From the Aaron Wilson article:
Another source noted that Harbaugh is extremely positive, consistent, and honest in his demeanor and dealings with players and coaches, countering the frequently cited narrative that Harbaugh can be difficult to deal with as completely false.
The reason Harbaugh got fired was simply that the 49ers CEO and owner, Jed York, 34 at the time, didn’t like Harbaugh, and Harbaugh reportedly didn’t like him.
But, if Adofo-Mensah, who knows Harbaugh, worked with him, and recommended interviewing him, thinks he can work with Harbaugh again as GM and head coach, that should be good for the Wilfs, who are normally a pretty hands-off ownership group when it comes to the day-to-day football operations.
