Sources: Nike signs Giants' Odell Beckham Jr. to richest NFL shoe deal

— -- After a competitive battle, Nike re-signed the most valuable football player on its roster in New York Giants wide receiver Odell Beckham Jr.

Terms were not disclosed, but sources with knowledge of the deal say it's a five-year deal worth in the neighborhood of $5 million a year -- the richest shoe deal for an NFL player and about two times more than any previous deal Nike had with a football player.

The deal will make Beckham a larger brand spokesman for Nike, including campaigns outside of football.

The deal got so big because Adidas wanted to take Beckham from Nike, sources said. Nike had the right to match the offer, which it did.

A Nike spokesman said the company wasn't commenting on the deal. The story was first reported by sneaker site NiceKicks.com.

"It was a long process," Beckham's agent, Zeke Sandhu, told ESPN. "This proved he's an icon."

Beckham's value not only comes from his flash on the field during games, but his ability to stay relevant off of it. He has 8.3 million Instagram followers, 2.3 million Twitter followers and 1.3 million Facebook followers.

He drew even more attention to himself and Nike with the shoes he wore before every game last year, customized by sneaker designer Troy Cole. One week, Beckham had Burberry Nikes; the next week, it was a "Back to the Future" tribute. Every design seemingly spread like wildfire on social media before games.

The deal was done by Sandhu and Beckham Jr.'s mother, Heather Van Norman, who is his business manager.

On the field, Beckham is in the final year of his original four-year rookie deal with the Giants. He's set to make $1,839,027 in 2017 -- meaning Nike will play him far more than New York.?

Other athletes who made more from Nike this season than from the team they play for include LeBron James and Kevin Durant.

The Giants recently exercised a fifth-year option for 2018, which will likely pay Beckham more than $8 million. He can become a free agent in 2019, if the Giants don't utilize the franchise tag.
