Beckham wants a new contract. He is set to play on the fifth-year option of his rookie deal this season for $8.5 million, well below the market value for a wide receiver of his ilk. He is a three-time Pro Bowl receiver and one of the league's top playmakers. The Giants stumbled to a 3-13 season last year with him sidelined by a broken ankle suffered in October.
"I anticipate that we'll be speaking with his agents sooner rather than later," Mara said. "I'm not going to give you an exact timetable on that or give daily or weekly updates on that. But I think those will start pretty soon, and hopefully we will come to an agreement."
Beckham reported for the start of training camp Monday, even without the Giants having shown any desire to get a new deal done this spring or early this summer. He also attended the start of OTAs and minicamp this spring.
This hasn't been lost on the Giants' brass after they discussed trading him in the offseason. Beckham elected to report to training camp while some others in his situation, such as Oakland's Khalil Mack and the Rams' Aaron Donald, have dug their heels into the ground and held out in hopes of a megadeal. The 2014 draft class is at a crossroads.
"It certainly had an effect on our desire to start negotiating," Mara said. "[Beckham's] had the right attitude all along and we expect him to have a great season."
Mara wouldn't say where he stood on whether Beckham is medically ready to participate in full-contact drills or preseason games. He deferred to coach Pat Shurmur and Beckham on that topic. Shurmur has said Beckham is "ready to go" but the Giants would be smart with him this summer coming off a serious injury.
Their first training camp practice takes place Thursday afternoon.
Beckham didn't participate in any live drills this spring, even though he was cleared for minicamp. There was clearly a desire to make sure he was progressing physically and personally before entering any negotiations.
"We certainly wanted to see what he could do on the field, wanted him to pass his physical," Mara said. "He obviously was here a little bit during the spring and we felt pretty good about where he is. We feel very good about where he is physically right now."
The Giants have a history of getting deals done with star players right before the start of the season. Extensions for Eli Manning and Plaxico Burress were finalized days or weeks before Week 1.
This could be the case again considering it's late July and they have not yet started negotiating. Beckham expressed a desire to be the NFL's highest-paid player last summer. While that might be unrealistic, he does want his next deal to make him the top-paid wide receiver.
"We think we know what it is going to take to re-sign him," Mara said. "We'll see."
It could take time for the two sides to find a happy medium. They're beginning rather late in the process with training camp having already commenced.
"I think this was the timing we always had in mind," Mara said. "I think Odell personally is moving in the right direction. I think he's come in here with a good attitude. Showed up [Monday] with a smile on his face and worked hard. I think he's ready to go. I think he's ready to have a great season. We're ready for him to have a great season."
The Giants open their season Sept. 9 at home against the Jacksonville Jaguars. They're hoping Beckham is there for that and beyond with a new contract.
"We obviously want him to be a Giant for a long time," Mara said, "and we hope to be able to come to some agreement."
