The new MLB playoff proposal is likely to happen because top TV executives love the idea of having more drama-filled, higher-rated, prime-time elimination games.

TV executives and baseball officials contacted by The Post universally supported the new ideas and felt the plan could lead to a more lucrative contracts with ESPN’s and TBS’ MLB packages expiring soon.

On top of the network and league officials, none other than Bob Costas, was also a supporter of the plan that would expand the number of playoff teams and create more intrigue for the playoffs.

“Something like this is going to happen,” Costas told The Post. “Generally speaking, I’m in favor of it. I find the concept behind it appealing. I find the television aspect appealing. The more meaningful postseason games you have, the better. I’m good with all of that.”

The proposal — the contents of which were reported by The Post’s Joel Sherman before MLB could even share it with the Players Association — has many elements executives liked, but none more so than the idea of increasing the number of elimination games.

During the World Series, a Game 7 usually rates around 60 percent better than any of games 1-6.

Though Fox owns World Series and playoff rights through 2028, ESPN/ABC is expected to make a big push for Turner’s playoff rights with CBS, possibly NBC and platforms like DAZN expected to, at least, hold talks.

For TV purposes in the proposed plan, between both the National and American leagues, there would be six series and potential for 12 elimination games in the opening round.

In the current format, there are just two elimination games from each league’s wild-card matchups.

After the opening three games of the new proposal, the playoffs would revert to the same two best-of-five divisional series in each league followed by the best-of-seven league championships and the World Series.

“This is maybe the first draft,” said Costas, who works for MLB Network. “But that doesn’t mean that we can’t fine tune it and hear from various credible precincts before we settle on a final format.”

Costas eventually envisioned MLB adding two expansion teams to have a total of 32 clubs in four eight-team divisions.

In this scenario, he thought it would be wise to study having two division winners in each league that would earn byes with the four wild cards playing in the best-of-three series.

This would mean 12 total playoff teams as opposed to the new formats’ 14. The current tournament qualifies 10 teams.

Any new plan won’t go into place until the 2022 season, which is when the new TV deals will begin.

In the current proposal, Costas said he liked the idea that the top teams would choose whom they would face.

“I like the pick-your-opponent part because it isn’t just, ‘Which team was the weakest team?’ ” Costas said. “What if one of those teams literally had to go to the last day of the season and use their entire pitching staff just to secure their spot. Or, since you have all the games in your park, maybe you are looking at the lineup of opponents. Does our park work for or against any of these teams? Or maybe our own lineup is left-handed heavy and one of these teams, even though their record isn’t as good, has a lefty leaning rotation that we have some concern about.”
