The article is mainly about Tygart defending the reduction of sentences if people confess/cooperate. Tygart points out that Tyson Gay gave up a silver medal he wouldn't have had to give up if he hadn't confessed.
He says that he offered Lance Armstong a six month ban if he confessed/cooperated.
He defending the us of plea bargains by saying, "holding distributors accountable is the only way we’re truly going to change the culture of a sport, as opposed to just penalising individual athletes when they’re dumb enough to get caught.".
The "dumb enough to get caught" line caught my attention and supports what Sports Gene author David Epstein has told me. If you know what you are doing, it's really hard to get caught in a positive test.
