PHOENIX -- Giants president and co-owner John Mara said he believes emotional wide receiver Odell Beckham Jr., who punched a hole in the wall at Lambeau Field after the Giants' playoff loss to the Packers in January, will deal with his temper better, that there is no reason to be concerned long-term about the receiver's mercurial personality and that Beckham is "the last guy on our team I'm worried about."
