(Toledo, OH) We built our deck about 12 years ago, pouring our heart, soul, and sweat into this two-level wooden masterpiece. Unfortunately, in the past two years there has been a noticeable sag in two of the external corners (farthest from the house).
I am hoping that a knowledgeable reader will offer suggestions on how best to rectify this sinking deck. At the moment, the worst of the corners has fallen about 10 degrees, which is enough to get me motivated and fix the problem.
My wife, the engineer, believes that if we dig a 2-3 foot deep cone-shaped hole around the posts, jack the deck up, and pour some cement, the deck will be stabilized. I, being the person in this relationship lacking any engineering qualifications whatsoever, believe that I need advice of an expert nature.

Or - if not expert advice - at least someone with some experience in these matters. Thus, if you have any thoughts whatsoever regarding the stabilization of sinking decks, feel free to weigh in with an opinion.
Also: my wife reads this blog, so be kind with any criticism. Hell hath no fury like an engineer scorned.
