There was undercover video, a shadowy guy with a lot of drugs in his refrigerator and not-entirely-corroborated allegations against a number of big-name athletes. It even questioned whether Denver Broncos quarterback Peyton Manning was linked to the doping industry. It came from Al Jazeera, the international news operation funded by the Qatari royal family.
