Shia LaBeouf has something to say to the Cavs and Warriors

Shia LaBeouf had a few words to help pump up the Cavs and the Warriors before the first game of the 2015 NBA Finals.

Using a motivational speech that LaBeouf recorded in front of a green screen last month, the video staff at Grantland created a hilarious mashup, which featured Shia telling everyone that in order to win they can't "let their dreams be dreams. Just do it!" Welcome to the NBA Finals.
