The Jets last made the playoffs in the 2010 season when they played in the AFC Championship game for the second straight year.
"There are good arguments on both sides, and I haven't gone into it in maybe the depth that we will," Johnson said this week, according to the Newark Star Ledger. "We're going to study it hard. But I kind of like it. I kind of like the idea of more playoff games. We're still below other sports (in the number of teams that qualify for the playoffs)."
The Jets have gone 8-8, 6-10 and 8-8 in the last three years since their last playoff appearance. That is two games worse than the Dallas Cowboys, whose owner Jerry Jones is also in favor of adding more teams to the playoffs.
"From the standpoint of looking at how exciting it is for a city or a community to be involved in the playoffs and the fact that you can have a team that might have literally operated at .500 or in that area ... you can have that team win the Super Bowl," Jones said in January. "That makes a big case for adding a couple of more cities or communities that have NFL teams to the playoffs.
"It just creates that much more excitement and that much more interest for people in those communities. So I fall on the side of the ledger that would increase the playoffs."
Last week, Pittsburgh Steelers president/co-owner Art Rooney II told Sports Business Daily that the team's ownership is open to playoff expansion.
"We're interested in looking at it," he said. "From the Pittsburgh perspective, we have an open mind about it. One more playoff game in the opening round would allow more fans to be alive in the competing cities."
Commissioner Roger Goodell said in May that he believes owners will approve expanding the postseason starting in the 2015 season.
"I think we want to see one more year of 'Will it impact the regular season in a positive way, from a competitive standpoint?' Will it create more excitement, more races toward the end?" Goodell said. "... And we also want to absorb the additional inventory into the marketplace, from an advertising standpoint. ...
"I spoke to (NFLPA president DeMaurice Smith) about it two weeks ago. I think there's a lot of benefits to the players. That's something they'll have to evaluate. ... I do believe this is a real benefit to the players. The revenue, obviously, will increase, and they share in that."
