The NFL overhauled how pass interferences can be called this offseason with coaches now allowed to challenge them, and New York Giants cornerback Janoris Jenkins didn't mince his words talking about what affect it might have on the league.

“I mean, it could be a train wreck,” Giants cornerback Janoris Jenkins told NJ Advance Media on Thursday. “We’ve got to deal with the consequences.”

The NFL has made it clear to overturn a pass interference call it has to be clear and obvious, but that also can be left up to interpretation. Giants wide receiver Russell Shepard wonders what exactly the league will decide is obvious and what isn't.

“How do you define that, blatant?” Shepard said. “I just don’t really know how to define blatant, as they say. I don’t think nobody at this point knows really how to define that, or what that looks like.”

Second-year referee Shawn Hochuli has traveled around to training camps trying to help teams understand the new rules and he has tried to emphasis one thing, the rules of pass interference haven't changed, the only thing that has changed is being able to throw a flag after a play is already completed.

Jenkins thinks that one of the other things that will hard to figure out is when a flag can be thrown, because how pass interferences are called change from week to week and based on how big of a game is being played.

“One week you’ll let certain teams play football,” Jenkins said. “And the next weekend, you’ll come and call the next game tight. Don’t be up and down. If it’s a playoff game or something exciting, let everybody play.
