The defenders are acting like it was just under 12.5 psi. They were 10.5 psi. Weather doesn't do this to this degree, and if it did, they played on their home field and easily would have picked up on it in the 15 years Brady has been there. They were clearly tampered with, and a ball boy doesn't go rogue and do this on his own. Anyone who can honestly defend Brady and/or Belichick is a complete idiot or sees the world through Patriot-colored glasses.
