BLOOMINGTON, Ind. (AP) — Indiana University athletics officials say they’re exploring their options for a more lucrative apparel contract as the school’s contract with Adidas nears its end.

The Hoosiers’ relationship with Adidas started in 2004. IU’s current $21 million Adidas contract was signed in 2008 and expires next year.

Jeremy Gray is IU’s associate athletic director for strategic communications. He tells The Indianapolis Star that the university is “very, very deep” in the process of looking at its options for its next apparel contract.

Gray says IU isn’t unhappy with its relationship with Adidas, but is just exploring its options.

College apparel contracts have grown increasingly larger in recent seasons, including a $90-million, 10-year deal with Under Armour that lured the University of Notre Dame away from Adidas last year.
