Plenty for new guy to learn about Boston

The Red Sox performed two very important good deeds the other day when Gordon Hayward arrived in Boston to kick the tires about possibly signing with the Celtics:

• When Hayward and his wife were driven to Fenway Park for a meet-and-greet with the historic ballpark, the Sox fired up the big screen in center field and delivered some come-hither: “Welcome to Boston Gordon and Robyn.”

• They did a sweep of the place to make sure insecure Sox lefty David Price wasn’t lurking in a corner, looking for some perceived slight to get worked up about. It all helped. Hayward agreed to a four-year deal with the Celtics for a reported $128 million and will be reunited with coach Brad Stevens, his mentor from the glory days at Butler.

But while the cheery Fenway message provided a fine example of how our big league sports franchises can work together for the common good (remember Tom Brady’s hopeful pitch to Kevin Durant last summer?), Gordon Hayward still has much to learn about Boston.

Here, then, is one man’s handy, dandy, welcome to Boston primer for the newest member of the Celtics:

• The Patriots (five), Red Sox (three), Celtics (one) and Bruins (one) have combined for 10 championships this century. This will be brought to your attention at the introductory press conference. It will get mentioned the first day of training camp, on Opening Night, during the All-Star break and any time you pop into Dunk’s for a regular and a cruller. Winning is a big deal around here.

• Watch “The Friends of Eddie Coyle,” which is still the best movie ever filmed in Boston. Robert Mitchum’s salute to Bobby Orr is solid gold.

• If it’s true you’ll be earning $128 million, good news: You can afford a house in Weston or Wellesley. But if that figure is on the shy side and you’re actually making much more than that — say, $180 million — I have even better news: You can now afford a house in Jamaica Plain or Somerville.

• Take a jog along the Charles River, being sure to traverse the little wooden bridge that runs under the BU Bridge. The view of the downtown skyline as you come around the bend is spectacular.

• Nobody in town knows more about the NBA than Glenn Ordway, who “retired” after a sterling career as play-by-play voice of the Celtics and later emerged as a super popular talk-show host on WEEI. If you meet Ordway, be sure to ask him about the time he landed a cameo on an episode of the smash-hit TV series “Cheers” that included a guest starring role for Kevin McHale. Better yet, just introduce yourself and Glenn will bring it up.

• Best hidden gem that’s in plain sight: Pavement, the little coffeeand-bagel place on Boylston Street, one block from Fenway.

• Gordon, you’re familiar with the Bonnie Situation from “Pulp Fiction,” right? Well, you’ve got a Brady Situation on your hands. Look, everyone is in on the joke: back in January, when you said, “Aaron Rodgers. I can’t stand Tom Brady,” in response to a question about which NFL quarterback you preferred, it was understood you were speaking as a lifelong Indianapolis Colts fan and not some Deflategate moralist. So say that when, inevitably, you get asked about it. Have some fun. Laugh about it. And do touch the third rail that is Deflategate.

• After your physical, hop in the car and go find a Cape Cod League game to watch. If you can’t get away, the Boston Park League, Intercity League or Yawkey League will do.

• Keep an eye and an ear out for opportunistic Celtics analyst Cedric Maxwell, who we hear is taking a crash summer course at the Dennis Eckersley School of Telling It Like It Is. And if a newly snarky Max starts dropping such bombs as, “Hayward missed that shot,” and, “Hayward got caught out of position on that one,” don’t stand for it. Be sure to berate, ridicule and flat-out scream at him on the next charter flight.

• Though practically a cliché at this point, the Gardner Museum really is a great place to spend an afternoon.

• As you make your peace with Brady, do not make the mistake of believing that ol’ No. 12 is the most important athlete in Boston. He’s not.

• Patrice Bergeron is not the most important athlete, either. • And nope, it’s not Isaiah Thomas. • Mookie Betts? Sorry. • The most important athlete in Boston is Pete Frates.
