Is Under Armour's roster of athlete endorsers too bland? Mark King, adidas' North America president, thinks so. In an interview with Yahoo! Finance, the exec criticized Under Armour's players as not being all that interesting.

"I think most of the athletes at Under Armour are kind of milquetoast," King said. "[Jordan] Spieth, [Tom] Brady, hey, they are great athletes, but when you talk about Carlos Correa and James Harden and some of these guys that have personality and really stand for being an individual, that’s unique positioning for us."

King did not mention by name Under Armour's biggest endorser, Steph Curry.

In the interview, King said that adidas is focused on athletes who are "creators" that "have individual personalities that try to carve out their own space."
