Deflate-Gate: New England Patriots Coach Says Team Will Cooperate With Probers

Bill Belichick says he didn't know about it until this morning.

"We'll cooperate fully with whatever the league wants us, whatever questions they ask us," Belichick said.

"I didn't know anything about it until this morning," he said in a conference call with reporters.

Deflated balls may be more difficult or easier to catch, depending on how much air is missing.

"I think I've heard it all at this point ... it's ridiculous," he said. "I don't even respond to stuff like this."

The NFL’s guidelines dictate that a ball must be inflated to about 12.5 and 13.5 pounds per square inch and weigh between 14 and 15 ounces.

"Officials check balls as they go into the game, and if the ball doesn't feel perfect, they can throw it out," former NFL official Jim Daopolous told ESPN. "There is always the possibility that balls can lose air due to the conditions."

The minimum disciplinary action for anyone, including the head coach or other club personnel, who is responsible for a non-approved football is a fine of $25,000, according to the NFL's game operations manual.
