They lost in the Super Bowl last season...
Yeah, a half-decade and two other regimes later.
They had success when Mariucci was the coach, inexplicably hired Dennis Erickson after Mooch lost in the divisional playoffs (after the Giants gifted them a win in that years wild-card) and then went on a "run" of futility for about 10 years with the likes of Erickson, Mike Nolan (cameo appearance by a certain fat piece of excrement who's been dragged to every professional success he ever had by Aaron Rodgers as offensive coordinator for a little while) and Mike Singletary (I WANT WINNERS!).
Harbaugh and to a very underrated extent, Vic Fangio get there and the team instantaneously rights the ship. He gets fired and its back to the outhouse with the likes of Jim Tomsula (special guest appearance by the Mangenius as defensive coordinator) and a year of Chip Kelly before Shanahan gets there and turns it around in year 3.
Shanahan's resurrected that franchise, but they went from the toilet, to going to three NFC title games in four years and a super bowl, back to the shitter.
Again, I'm nowhere near as jazzed by a Harbaugh hire as I would've been two years ago, but I won't be pissed either. The ultimate meh hire.
I'm good with anybody but Adam Gase, Jim Harbaugh, and Eric Bieniemy.
This ownership is totally capable of hiring fuckin Marty Morhinweg.
