EAST RUTHERFORD, N.J. — Just past 8 p.m. Monday, as the Cleveland Browns ran onto the field at MetLife Stadium, the grandstand erupted with boos and jeers.
It was a familiar response for a visiting opponent at an N.F.L. game. But, clearly, Odell Beckham Jr., who was jogging alongside his Browns teammates, did not think it was meant for him.
This was his moment and his stage — his first game back at MetLife, albeit against the Jets, since the March trade that ended Beckham’s five eventful years as the cynosure of mostly desultory Giants teams.
