This is not a book review of “Baseball Maverick: How Sandy Alderson Revolutionized Baseball and Revived the Mets.” That would be unfair, because I stopped reading at about 100 pages.

I felt I had the gist of the book by then — Alderson is a do-no-wrong genius, everyone else not so much.

You really do not have to get through more than the 20-page prologue to see how Alderson is set in heroic light and, in the case of the opening of the book, hired as Mets general manager to clean up Omar Minaya’s mess.

So it is not a book report I want to do as much as, hopefully, provide a more accurate accounting of history. Because if the Mets truly are “Revived,” as the sub head of this book suggests, then Alderson owes gratitude to his predecessor.

To be clear, Alderson is not the author of the book, and he has — to my knowledge — never publicly disparaged Minaya. In fact, at an event at the Yogi Berra Museum & Learning Center at Montclair State University on Saturday, he told The Post’s George Willis,“I don’t attempt to take credit. My job is to manage and direct an organization. We still have a lot of people who were here with Omar before.”

Nevertheless, he gave behind-the-scenes access and scads of interviews to Steve Kettmann, who has known Alderson for more than two decades. If there were a sentence Alderson would change in the book, I did not come across it in my 100-page journey.

A fair-minded editor, though, might have suggested an alteration in, at least, the tone. Even in the prologue you can get a sense of where matters might be going, as the author makes it clear Minaya left a couple of albatrosses behind in Jason Bay and Francisco Rodriguez. Though in referring to another piece left behind, Matt Harvey, the wording is tempered to “Minaya had landed a good one there.”

A good one?

Any GM would take working through three Jason Bays to have one Matt Harvey. The Mets were building their dreams this spring on what Harvey and Jacob deGrom could give them out of the rotation. They extended the contract of Juan Lagares because they saw him as a cornerstone on the rise and, for the same reason, tried to extend Lucas Duda. You know what those four players have in common? Minaya brought them to the Mets.

Which makes it interesting that in the first paragraph of the book — the very first paragraph — Kettmann writes it was Alderson’s priority when taking over the Mets was to “rebuild a barren farm system.” If a drought were this barren, it would be called an oasis.

The majority of the prologue revolves around how shrewd Alderson was to turn Carlos Beltran into Zack Wheeler. And he was. This is not meant as a takedown of Alderson, whom I endorsed to replace Minaya, and whose patience and thoughtfulness steadily have allowed the Mets to accumulate assets. But to buy a million-dollar house you need access to a million dollars, and to obtain Wheeler, you needed something that would entice the Giants. And Beltran was signed by Minaya.

The 2015 Mets remain, at the least, as much a reflection on their last GM as their current one. Duda, Daniel Murphy, Wilmer Flores, Lagares, Kirk Nieuwenhuis, Ruben Tejada, Jeurys Familia, Bobby Parnell, the now-suspended Jenrry Mejia and four-fifths of the rotation — Harvey, deGrom, Dillon Gee and Jon Niese — were brought in by Minaya, and David Wright was drafted when Minaya was the assistant GM.

Minaya signed a junk-heap pitcher named R.A. Dickey, whom Alderson translated into Travis d’Arnaud and Noah Syndergaard. Lefty specialist Josh Edgin, a part of Minaya’s last draft class (2010), was lost for the season (Tommy John surgery), so another member of that class (Matt den Dekker) was dealt to Washington for Jerry Blevins.

Steve Matz, possibly the Mets’ best pitching prospect, was drafted in 2009.

Now, Minaya’s record is Minaya’s record. He was far from a perfect GM. He was too disorganized at times and too often veered from one strategy to the next, and when the club began to teeter, he lacked the skills to fix the roster in real time. Minaya did not hand Alderson, say, what Gene Michael/Bob Watson baton-passed to one of their assistants, Brian Cashman, in 1998 — a championship-worthy team.

But the book elevates Alderson to baseball heroism for how he dealt with the post-Madoff financial stranglehold on payroll. But he only could do that in a generally positive fashion because he had inexpensive, homegrown talent available — Minaya’s inexpensive homegrown talent.

Consider that on Opening Day rosters (which include active players, those on the disabled list and those on the restricted list), the Mets were tied with the Phillies for the most homegrown players (16). Fourteen were from Minaya’s GM administration, plus Wright and Rafael Montero, who was an international signing by Alderson.

There were 21 players on Opening Day rosters throughout the majors who either were drafted or signed as international free agents by the Mets during Minaya’s 2005-10 tenure. That includes high-end players now elsewhere — such as Joe Smith, Collin McHugh and Jose Quintana. Just the Braves (25) and Cardinals (22) had more players signed to their first pro contract in that time frame still in the majors than Minaya’s Mets. By comparison, the Yankees had 15.

This merely reflects volume and not definitive quality, and lack of volume does not assure non-contention. Oakland, for example, was tied for the fewest in this category (eight), but Alderson’s protégé, Billy Beane, has shown himself to be an unafraid master trader.

Plus, players brought into pro ball from 2005-10 should be a significant part of prime-aged players in the majors in 2015. It is only now — with Montero and Danny Muno with the Mets, Logan Verrett with the Rangers and Cory Mazzoni being used to land Alex Torres — that we are seeing the first of Alderson’s players breaking through or becoming useful chips. And, of course, his administration should be praised for refining the skills of deGrom, Duda and Lagares, etc.

But those players’ presence, and that of Harvey and Familia and others, suggest Alderson did not take over a “barren farm system.” And if these Mets truly are “Revived,” then the co-author of that book is named Omar Minaya.
