To mark Stephen Curry's 2014-15 Kia NBA Most Valuable Player Award, Under Armour released this ad narrated by NBA legend Bill Russell chronicling the player's determination and commitment to the game. As we watch Curry practicing, Russell recounts the credo of a stonecutter who hammers away at a rock, not knowing when, but believing his hammer will eventually split it open. The powerful narration ends just as Curry scores. Droga5 New York created the spot.

Under Armour is also releasing a special colorway of the Curry One basketball shoe online and at selected retailers in June.
