In a clandestine meeting at a DoubleTree by Hilton conference room in Grand Rapids, Mich., in late March 1987, Pete Rozelle, Paul Tagliabue and Roger Goodell secretly hatched a plan for worldwide, round-the-clock NFL expansion, according to multiple people at or near the gathering who are unauthorized to speak publicly about the undertaking because they might not even know what they’re talking about.

And, from all indications, this covert NFL manifesto is now in its final stages.

Here is what the NFL is considering for as early as the 2021 season, according to a report by CBSsports.com:

●Add a 17th game to the regular season and a second bye week.

●The additional game for each team would be played out of market.

●There would be out-of-market games every week internationally or in U.S. cities without a team.

●Add a wild-card playoff game in each conference.

●Move the Super Bowl to the end of February.

Impressively, the NFL is considering doing all of this in the face of growing science about neurological damage to its players and growing resistance from parents about allowing their kids to play football.

Then again, the NFL still retains a pervasive hold on much of the sporting public. Heck, the NFL could have sold Sunday Ticket packages to passengers on the Titanic.

Although the NFL has not added a team since the Houston Texans became its 32nd franchise in 2002, the league has continued to expand in other ways, including scheduling games as many as four days a week and playing multiple games annually in England and Mexico.

Frankly, I believe the NFL should stop its tiptoe crawl toward global domination and rather stomp its feet en route to replicating the British Empire of the early 20th century.

My NFL plan is bolder, brasher and more in line with Jerry Jones’s wildest, non-Jason Garrett hopes:

●A 32-game regular season schedule.

●Expand to 48 teams.

●Back legislation to change the calendar to better oblige NFL scheduling needs.

Let’s start with this 17th game the league is pondering. One more game? What’s that? Reminds me of the U.S. Postal Service upping the cost of stamps two or three cents at a time. JUST GO FOR IT; double the length of the season, for goodness’ sake. More replays! More comebacks! More records! More injuries!

I mean, if they had already done this, Matthew Stafford could have made it to 100,000 passing yards by now without ever winning a playoff game.

By growing to 48 franchises, the NFL can put teams in London, Mexico City, Moscow, Hong Kong, Montreal, Pyongyang, San Antonio, Anchorage, San Diego, Kenosha, Wis., Tunica, Miss., Trinidad and Tobago, Paris (France), Paris (Tex.) and Monowi, Neb.

I’d also contemplate taking the Jaguars out of Jacksonville, because nobody ever goes to Jacksonville unless they are already in Jacksonville.

To accommodate this bloated enterprise — and allow the NFL to better command the nation’s TV programming — the key would be to replace the seven-day, 52-week year with a six-day, 60-week year.*

(* If you give Donald Trump a team while he is still in the White House — Eric can run it — he will back this calendar change with or without congressional approval.)

Just get rid of Tuesdays — Tuesdays are for losers — and then the NFL could broadcast games on Sunday, Monday, Thursday, Friday and Saturday; this would leave Wednesday for ESPN to run an all-day NFL studio bonanza blowout in which 24 of its talking heads debate Stephen A. Smith one hour at a time on various league topics.

Sure, some snowflakes probably will whine about player safety concerns over a nearly year-round season. Not a problem. Through a unique fan promotion that will ensure sellouts every week, if the last available player on the home-team roster gets hurt, one eligible season ticket holder’s name will be pulled from a hat, and that fan will play the rest of the game!

And with in-game betting apps on the horizon, this means you’ll be able to watch, gamble on and even play in an NFL game all for the price of a ticket. Wow.
