On Monday, that reportedly became reality when Beckham and the team agreed to a five-year contract that will make him the NFL's highest-paid receiver.
According to reports, Beckham Jr.'s new deal is worth $95 million, including $65 million guaranteed, making him the highest-paid wide receiver in the NFL.
Beckham is set to make $8.4 million on the fifth-year option of his rookie contract.
"Honestly, I don't even know how to explain it", said Beckham.
The contract extension marked the best-case resolution for Beckham who had his Giants future in doubt after a hard offseason.
Beckham, popularly known simply as "OBJ", shot to global prominence in his rookie season after making an astonishing one-handed catch in a game against the Dallas Cowboys that many pundits acclaimed as one of the greatest catches in National Football League history. "I don't know if it's a relief, I don't know - it's a combination of everything".
The three-time Pro Bowler has caught 313 passes for 4,424 yards and 38 touchdowns in 47 games over four seasons.
"I knew that it would get done; it just was a matter of when".
The contract includes a guaranteed $65m and an average $20m over the first three seasons for the star player.
The Giants selected Beckham with the 12th overall pick in the 2014 draft.
