If football were fake, then deflategate wouldn't have happened.
I am a huge Federer fan and, after his 5-year grand slam drought and surgery, I have no doubt that he is earning his comeback. Just looking at his play now -- his dominance on the court and his new play style (hugging the baseline and half-volleying) tells me he's new and improved, and the results speak for themselves. A few years ago, Davydenko was paid to take a dive and was suspended by the ATP.
Some sports are definitely rigged; some sports definitely aren't.
