Gene Steratore, the head official in the crew that worked the NFC division game between the Green Bay Packers and Dallas Cowboys, met with a pool reporter after the game to explain the decision to overturn a catch by Cowboys wide receiver Dez Bryant.

“Although the receiver is possessing the football, he must maintain possession of that football throughout the entire process of the catch,” Steratore said. “In our judgement he maintained possession but continued to fall and never had another act common to the game. We deemed that by our judgment to be the full process of the catch, and at the time he lands and the ball hits the ground, it comes loose as it hits the ground, which would make that incomplete; although he re-possesses it, it does contact the ground when he reaches so the repossession is irrelevant because it was ruled an incomplete pass when we had the ball hit the ground.”

Bryant hauled in the fourth-down pass at the Packers’ 1; Coach Mike McCarthy challenged the call and it was reversed. “When you’re still going through the process of the catch, elbows or knees are irrelevant, he must complete that entire process with the football, maintain possession throughout,” Steratore said.

Steratore, of course, has been here before. He overturned a game-winning touchdown in 2010 by the Detroit Lions’ Calvin Johnson, using the “entire process of the catch rule.” That’s why this is called the Calvin Johnson rule.
