I’ve always been fond of the word “blockbuster.” I mean it’s just one of those words you hear only in regard to one thing: A trade.

Buster Posey and the San Francisco Giants this week put together the kind of “blockbuster” that hasn’t been seen in these parts for many years.

Posey tore a page out of the Brian Sabean playbook and simply went for it. And what he got and what he gave up, right now and on paper, seems to be exactly the infusion that this team needs to prove this season is not an aberration.

Nothing, of course, is a guarantee, but Rafael Devers — unless he forgets how to make square contact with a round bat overnight, is a hitter. And, the universal thought before this “blockbuster,” was that the Giants’ greatest need was offensive punch. Hello Raffy.

And, despite what some Red Sox fans and ex-players moan about, all reports about this guy that we hear, are positive. He’s quiet — almost introverted in public. This was apparent at his press conference. He answered questions, he didn’t expound. No problem.

He’ll fit into this clubhouse because he’s not a “yahoo.” Matt Champion, Willy Adames and Justin Verlander are the clubhouse adults. Devers just needs to blend — not necessarily lead.

Peers call him Carita (little face in Spanish), because he looks young and innocent.

He is a student of the game who is dedicated to improving his defensive skills.

He’s in the right place.

Generally there are only two words to be heard in response to the story of a “blockbuster” trade, either “Wow!” or “Who?”

This week, the Giants provided their fans with the first “wow” trade the team has made since they sent Matt Williams off to Cleveland in 1996 and got back Jeff Kent, Jose Vizcaino, and pitchers Julian Tavarez and Joe Roja.

Jeff Kent was a big asset for the team despite an open feud with resident super-star Barry Bonds. Vizcaino was serviceable for a short time as was Tavarez. Roja — not so much.

Two other “blockbusters” had mixed results. In 1987 Brian Sabean pulled the strings of a deal that sent three Giants’ pitchers: Keith Comstock, Mark Davis and Mark Grant, and third baseman Chris Brown to San Diego for pitchers Dave Dravecky and Craig Lefferts, and outfielder Kevin Mitchell.

Grant was the only ex-Giant to provide San Diego with anything (and that was mostly as one of the team’s broadcasters, which he is to this day), while Dravecky went 7-5 that year with three shutouts for the good guys. All Kevin Mitchell did in his stay was win the league’s MVP award. A blockbuster indeed.

And then there was the infamous 1966 “blockbuster” that saw the Giants swap Orlando Cepeda to the St. Louis Cardinals for Ray Sadecki.

Now this one goes down as perhaps the greatest example of a “what were you possibly thinking” trades of all time. True, the Giants had a guy named McCovey playing first base — Cepeda’s natural position, but you’d think they’d find a place to keep Orlando’s bat in the lineup too. I guess you could say they did. But it was in St. Louis.

In exchange, they got a left-handed pitcher who had won 20 games a couple of years earlier. Cepeda won an MVP award with the Cardinals. Sadecki was 3-7 with a 5.40 ERA that year with the G’s, and 32-39 in his four years with the team. This was a blockbuster with emphasis on the word “bust,”

And lest you think “blockbuster” trades in the Bay Area sometimes go awry only in baseball, let me offer you a couple of doozies from the other two major sports in this area.

The San Francisco 49ers in 1961 were an innovative team that decided that year to go with a never before seen formation called “The Shotgun.” They had four quarterbacks on the roster and decided that the oldest, Y.A. Tittle just wasn’t athletic enough to handle that offense.

So John Brodie, Billy Kilmer and Bobby Waters alternated on every play and Y.A. Tittle was considered expendable.

The Niners made a trade that would go down in team history as its worst ever. Tittle was sent to the New York Giants for a guard named Lou Cordelione.

Y.A. was in three straight championship games with the Giants, won the league MVP and had his number retired by the team.

Cordelione hardly saw the field in 1961, was traded to the Rams the next year and played for five different teams in six uneventful NFL season.

In a quote that typified the trade, Cordelione was quoted as saying, when informed of the trade, “Me? Even up for Y.A. Tittle? You’ve got to be kidding.”

And finally, the then-San Francisco Warriors had a big man who owner Franklin Mieuli, thought was making just too much money and was simply unaffordable. So he traded Wilt Chamberlain to the Philadelphia 76ers in exchange for Paulie Newmann, Connie Dierking and Lee Shaffer — plus a boatload of cash.

Newmann, Shaffer and Dierking were useful players but Wilt Chamberlain was an all-world player. The Warriors wallowed for a few years while the 76ers were world champions.

Franklin Mieuli was the last of a breed. He got the money to buy the Warriors by selling a flower stand. He wore a deerstalker hat and rode a motorcycle. The team’s office was in the basement of the Bellevue Hotel in downtown San Francisco. They played at the Cow Palace and what is now the Bill Graham Auditorium. He wrote the checks, and Chamberlain was just too expensive.

I’m still not sure how far the Giants can go this year. What’s more certain to me is that there is an intriguing combination of youth and experience on this roster. It’s a good no-nonsense clubhouse, and it’s assured to stay that way because of lengthy contracts to key players.

It still may be a year too early to bet the house on this year’s team. But I’ll be making a bee line to the “futures” window.
