Fickell will still look to hire a QB coach, presumably. If Grimes is the hire, it appears they're trying to build through the O-Line, which is the right move, IMO. I believe Harbaugh went back to heavy sets and a punishing O-Line after being on the hotseat in Michigan after a few lackluster years. Lucky for Harbaugh, the defense also vastly improved; we'll see if that's the case for UW.
I'll be curious who Fickell can get to coach quarterbacks. I'm not sure if there's a "reclamation project" out there that just wants to work to rebuild their coaching credibility or an up and coming type. It's another important hire for Fickell.
