There's a reason ESPN has pulled out of its coproduction with PBS on a documentary for Frontline. The piece, which was 15 months in the making, was called League of Denial, and was based on the investigative work of the Fainaru brothers - who write for ESPN. If the name Mark Fainaru-Wada sounds familiar, it's because he's been at the forefront of the ESPN's investigations into PED use in baseball for years, and has a spotless reputation for journalistic integrity.
