ORLANDO — Odell Beckham wasn’t on the field for the final 10 games of last season because of a broken ankle, but it sounds like the Giants star might be willing to keep himself on the sidelines with a holdout in 2018.After Giants co-owner John Mara expressed disappointment in Beckham’s decision-making as it relates to a string of stories and said the Giants will listen to trade offers on all players, Beckham’s camp apparently fired back and pushed things toward a stand-off.NFL Network’s Ian Rapoport reported that the Pro Bowl wide receiver does not plan to take the field in 2018 without a contract extension. The Giants are not ready to acknowledge the possibility, however.Biggest questions for Dave Gettleman, Pat Shurmur at NFL meetings”At the moment, it’s hypothetical,” Giants co-owner Steve Tisch said Monday at the NFL Annual Meeting. “We have not been contacted by anyone representing Odell making that comment or suggesting that’s something he will do.”My reaction is it’s another hypothetical situation in a number of hypothetical situations. Odell’s contract will be negotiated at the appropriate time. So to speculate on the what-ifs and what-would-you-do and if-this-happens-what-will-happen, I can’t do that. It’s not realistic and it’s not in anyone’s best interest.”Beckham is scheduled to make $8.5 million on the fifth-year team option of his rookie contract in 2018. Negotiations on a long-term extension have been a dominant topic for more than a year, with Beckham skipping all of the “voluntary” workouts last offseason.Expect him to pull that card again.But the Giants changed general managers and head coaches in December, and it appears the talks with Beckham’s agent — who has not returned several messages from NJ Advance Media — started over.”At the moment,” Tisch said, “conversations between Dave Gettleman and Odell’s representatives are at the earliest, most premature stages.”Tisch and Beckham unintentionally crossed paths one night this offseason in Los Angeles — where Tisch lives and Beckham is rehabbing — but didn’t discuss football.Tisch, who is a film and television producer, knows good drama can captivate an audience. He also knows that sometimes it becomes too much to be worth the trouble.
