This is an interview with an anonymous "bag man" at a big time college football program where he discusses shuffling money to recruits and current players. Pretty eye opening.
Real good stuff in there:

The rules of communication tend to follow your typical sleeper cell or drug-dealing outfit. Talk in person as much as possible, preferably in group settings. Don't use email. Never interact with the media and avoid the university's public relations or sports information departments whenever possible. And buy burners. Lots of burners.
