They kept the GM who did hire that HC, brought in QB that was kicked to the curb after the 1st season and then gave up major draft capital to bring in another QB. This “new” QB wants to be the center of the offense in spite of the fact that he's been showing signs that he's been washed up for the last 2 or 3 seasons.
Furthermore, as I said before, Harbaugh built his SB team on having a great D and running game. Furthermore, this GM has traded our best pass rushers away each of the last 2 years prior to each season’s trade deadline. His O was never centered on his QBs, but his RBs. His falling out with the 49ers occurred when they paid the QB as if he was the center of the O, forcing them to downgrade their D.
Finally, according to some sources, these owners may have ordered the GM to give the possibility washed up QB a salary that only an elite QB in his prime should be offered. If this can be verified, then that gives legitimate reason to be concerned Mr. Walmart is more like Jerry Jones or Dan Snyder then the Rooneys.
Looking at this from what kind of coach Harbaugh has shown himself to be over the years, or any other highly sought-after HC, why would any of them want to work for this organization at time? If Mr. Walmart wises up and models himself after the Rooneys in the future, then we might talk a higher sought-after HC here. However, if they did order the GM to give Wilson that huge extension, then we have a basis to concerned as far as what kind of owners they are at this time.
