ESPN's 30 for 30 will re-air 'Believeland' later this month...but it will have a different ending.

The documentary focused on the past failures of Cleveland sports teams—The Fumble, The Drive, The Shot, etc.

But after the Cavs' win on Sunday, they're changing that ending to a more positive one.

The new version will air June 30 at 8 p.m. on ESPN.
