Further information: New Orleans Saints bounty scandal
In March 2012, Goodell revealed evidence that players and coaches on the New Orleans Saints had instituted a bounty program in which Saints defensive players were paid bonuses for deliberately knocking opposing players out of games. Then-defensive coordinator Gregg Williams administered the program, and as many as 27 Saints defensive players were involved. Later that month, Goodell handed down some of the harshest penalties in NFL history. He suspended Williams, who had left to become defensive coordinator of the St. Louis Rams, indefinitely (Williams would later be reinstated at the start of the 2013 season). Goodell also suspended head coach Sean Payton for the entire 2012 season, general manager Mickey Loomis for eight games and assistant head coach Joe Vitt for six games. Additionally, the Saints themselves were fined a league maximum $500,000 and had to forfeit their second round draft picks in 2012 and 2013.[37] Goodell was particularly upset that those involved in the program lied about it during two separate league investigations of the program. Sanctions for players were not handed down at the time, and Goodell stated he would refrain from penalizing players until the NFLPA completed its investigation of the affair.[38]"
