San Jose Mercury News columnist Tim Kawakami has tweeted that two of his NFL sources "reiterated" that Jed York is focused on Jon Gruden and Jim Harbaugh as potential head coaches for the 49ers. As Kawakami stated, this would help focus in the GM options. While the GM will hire the coach, I'd imagine Jed York will want to be on the same page with the GM when it comes to philosophy of coaches to hire. That's not exactly breaking news if you look around the Twitter world.
There are going to be numerous reports of sources indicating this or that about the 49ers GM and head coach search, so we certainly would need to take all of this with a grain of salt. I'm always a bit suspect of anonymous sources, but that doesn't mean I don't think the Harbaugh/Gruden information is inaccurate. Rather, it's one source at this point. And as far as this affecting the GM search, it's not like Harbaugh and Gruden are some obscure coaches that could have a drastic impact on the GM search process. These are two guys in which I would imagine a lot of GMs would have some level of interest. So for now, just file this in your memory as one more tidbit in what will be a crazy, twisting journey over the next two to four weeks.
