You know exactly what I said, but you're inability to state your case makes you swing for snide remarks instead. Prove that Jim Harbaugh, through his motivational, organizational and CEO-esque responsibilities, as you allege them to be, have improved the 49ers drastically.
For one, the 49ers power structure was much different than the one Rivera stepped into, where Hurney had assembled himself a personal fiefdom by keeping the front office small and being directly involved in almost every aspect of the franchise; whereas Trent Baalke was an internal promotion and engages in more of a power-sharing arrangement with Harbaugh. Two, Harbaugh's immediate predecessor was one of the worst coaches in recent history, legitimately affecting the performance of his team and publicly humiliating them, which led to a talented team underperforming and made the next coach seem almost savant-like by the mere process of being competent. In contrast, Rivera came in for John Fox, who may have run his course here but is clearly a much superior coach to Singletary, so while the 2-14 season of 2010 was subpar it wasn't as if the team was drastically underperforming with Clausen at QB. Ironically, between the two coaches, Rivera is the only one to have improved his record from year to year 
You're trying very hard to make an argument for Harbaugh, but doing a remarkably poor job of giving any concrete evidence.
Once again, you're being recalcitrant and trying to purport a false argument ("prove that Harbaugh is actually a good manager", despite the fact that we haven't heard any fall out on him making bad moves--like with Rivera, and have heard nothing but praise from fans, reporters and players, regarding the very same thing), suited to your own conclusions/speculations.
Go ask Colin Kaepernick or Alex Smith, about Harbaugh's management, talent evaluation, procurement, courage or decision making skills? One of them was a career bust, who was great last year. Now he's sitting on the bench, watching a raw, unproven QB take his job and win the same NFC Championship they lost last year with him at the helm.
And the last that I knew, Harbaugh's team is going to the super bowl, which is an improvement over what they did the previous year. I'm sure any coach, would take one less loss, or a lesser regular season record to make the Superbowl after losing during the Conference Finals the previous year. This fact truly shows how out of touch you're apparent blind, rabid infatuation of Harbaugh, has pushed you over the edge of clear thinking.
So if anyone is not making their argument here (and continually slipping into a slippery slope of confounding murkiness), it would be you. But that's okay. It was a good chat.
We'll just have to agree to disagree, and let it go. I'm glad you feel so strongly about your thoughts.
