​Don't worry, J.R. Smith, you weren't the only one to think you ​were up at the end of Game 1. As it turns out, ESPN radio broadcaster Mark Kestecher also thought Cleveland was ahead108-107 in the closing seconds on Thursday night, and went on to celebrate Cleveland's win after time expired. Just one problem with that: 

​​Yup, it was 107-107 at the end of regulation. 

Just when you thought Smith was the biggest fool on the planet, he lands himself some company. 

The Warriors went on to dominate overtime play to take Game 1 of the NBA finals. Smith has come out and ​admitted to his major mistake. Hopefully in Game 2, Smith and Kestecher step their games up down the stretch.
