Among the biggest names on the list are North Carolina State pass-rusher Bradley Chubb, Florida State safety Derwin James and Alabama safety Minkah Fitzpatrick.
Meanwhile, a pair of receivers already in the NFL, Keenan Allen and Stefon Diggs, have also signed sponsorship deals with the shoe company.
Both players previously wore Under Armour apparel.
Allen is coming off the best year of his career, setting personal bests with 102 catches and 1,393 yards to earn his first Pro Bowl appearance. Diggs scored a career-high eight touchdowns in just 14 games this year, becoming a household name with his game-winning score as time expired in a playoff win over the Saints.
Meanwhile, Adidas has gotten ahead of the game by adding several prospects who have a chance to be impact players at the next level.
Six of the players signed by the company were in the final first-round mock draft from Bleacher Report's Doug Farrar. In addition to Chubb, Fitzpatrick and James, prospects like Jaire Alexander, Mike Hughes, Courtland Sutton, Christian Kirk, James Washington, Sony Michel and Rashaan Evans are all capable of going off the board in Round 1.
Adidas has done a good job of identifying young talent in the past, signing Alvin Kamara and Dak Prescott to deals before each of them earned Offensive Rookie of the Year awards. Aaron Rodgers and Von Miller are among the NFL veterans already part of the organization's roster.
