The NFL's policy on performance enhancing drugs rewards players who snitch on their teammates.

“The NFL Management Council may, prior to the conclusion of a Player’s appeal, reduce the length of the suspension and corresponding bonus forfeiture by up to 50% when the Player has provided full and complete assistance (including hearing testimony if required) to the Management Council which results in the finding of an additional violation of the Policy by another Player, coach, trainer or other person subject to this Policy,” the policy states.

A player facing a four-game suspension can potentially cut their suspension in half if they provide information on a teammate, coach or trainer.
