The NFL has "leaping" rules in place on field-goal attempts, but if you're athletic enough then there's a loophole. Well, the NFL reportedly is trying to close that loophole as officials meet with one another this offseason.

NFL competition committee is likely to propose ban on field goal and extra point 'leaps,' source said, as suggested by NFLPA at combine. — MarkMaske (@MarkMaske) March 20, 2017

The loophole is being able to time the snap perfectly and jump over everyone on both lines without the assist of others. If you put your hands on a teammate to help you jump, then it's illegal. The task is extremely difficult to do, but Kam Chancellor managed to pull it off twice in a 2015 game against the Panthers.

Another Seahawks player, Bobby Wagner, did it last season against Arizona. After the game, Cardinals coach Bruce Arians vented about the play, and said it needs to be removed.

“The Competition Committee went through that play and the officials wanted it taken out,” Arians said in October. “The committee left it in, but it cannot be officiated. Whether he touches, whether it was leverage, was his foot within the framework of the defensive lineman’s feet before he jumped, all those things that go into that call, I think it’s bad for football.

The NFL itself was impressed enough with Wagner's move last year that it even tweeted video of the play — with an all-caps "BLOCKED" and "Wow."

Arians is likely upset with this because his NFC West foe, the Seahawks, seem to have mastered it. Chancellor even tweeted his frustrations Monday afternoon about the proposed rule change. Wagner joined in as well.

They are trying to turn our league more and more into the #NoFunLeague — The Enforcer (@Kam_Chancellor) March 20, 2017

@SiriusXMNFL @Kam_Chancellor they shouldn't. It's fun jumping, I think the fans like it too — Bobby Wagner (@Bwagz54) March 20, 2017

The play doesn't happen too often considering its difficulty, but it's clear the NFLPA sees it as a danger to players.
