The NFL's investigation into the New Orleans Saints has focused on the bounty program, where players were rewarded for big hits and injuring players on the opposing team. But the Saints also broke another rule by allowing cash payments between themselves for big plays like interceptions.
The NFL's statement reads:
During the 2009, 2010 and 2011 seasons, the players and other participants involved used their own money to fund a "Pay for Performance" program. Players earned cash awards for plays such as interceptions or fumble recoveries.
In addition to the bounty program, Saints players broke the rules by paying cash for interceptions and fumble recoveries. which isn't allowed. It could be a violation of the salary cap, no matter how small the amount of cash it is.
But that's the small rule that they broke. The big one is rewarding each other for injuring other players and it will cost them when the Commissioner hands down his discipline.
