Odell “Odell” Beckham Jr. was a rookie who was expected to start in 2017.
Instead, he spent most of the offseason working with the Giants’ training staff to develop his speed and agility, the team said.
The team was excited about him and were confident he could play in the NFL, a team spokesman said.
He got his chance with the first preseason game in April and was impressive in his first three games, completing 15-of-18 passes for 166 yards and two touchdowns.
The Giants signed him to a one-year, $2.1 million deal in December.
They also signed him for the final year of his rookie contract.
Beckham, the first of the Beckhams to be drafted in the first round, has a long track record of success.
He was a first-round pick by the Miami Dolphins in 2010 and went on to become the team’s franchise receiver.
The Giants also had success with their other first-rounder, tight end Jared Cook, who has since been released.
Cook spent all of last season with the Kansas City Chiefs, but he signed a two-year contract extension with the New York Giants in June.
He had just four catches for 38 yards in the Giants season finale.
He is still owed $4 million this year.
The team has been trying to keep Beckham from getting injured in training camp, and the plan was to make sure he could keep doing what he does best: catch the football.
Beckership came at a cost.
Beckham is now a free agent.
The club is also paying $12 million in salary cap space to sign him, but that is expected to increase to $15 million next season.
Beckkins contract could become a sticking point between the team and the Giants in a year that could see the team move on from its top free-agent receiver.
Beckes contract could also become a stumbling block for the Giants, who could still try to re-sign him before the start of free agency in 2019.
The New York Jets are one of the teams reportedly interested in signing Beckham, who spent last season playing for the team in Kansas City.
