Brees reacted quickly to the news on Twitter, writing: "I am speechless. Sean Payton is a great man, coach, and mentor. ... I need to hear an explanation for this punishment."
The Saints now must decide who will coach the team in Payton's place — his suspension takes effect April 1 — and who will make roster moves while Loomis is out. There was no immediate word from the Saints, but two candidates to take over coaching duties are defensive coordinator Steve Spagnuolo and offensive coordinator Pete Carmichael Jr. Spagnuolo has NFL head coaching experience; Carmichael does not, but has been with the club since 2006.
When the NFL first made its investigation public on March 2, Williams admitted to — and apologized for — running the program while in charge of the Saints' defense. He was hired in January by the St. Louis Rams; head coach Jeff Fisher said Wednesday he'll probably use a committee of coaches to replace Williams in 2012.
Goodell will review Williams' status after the upcoming season and decide whether he can return.
"I accept full responsibility for my actions," Williams said in a statement issued by the Rams. "I will continue to cooperate fully with the league and its investigation and ... I will do everything possible to re-earn the respect of my colleagues, the NFL and its players in hopes of returning to coaching in the future."
While some players who played for Williams elsewhere said he oversaw bounty systems there, too, the league said its interviews didn't find evidence that "programs at other clubs involved targeting opposing players or rewarding players for injuring an opponent." But Goodell could re-open the case if new information emerges.
After the NFL made clear that punishments for the Saints were looming, Payton and Loomis took the blame for violations that they acknowledged "happened under our watch" and said club owner Tom Benson "had nothing to do" with the bounty pool, which reached as much as $50,000 during the season New Orleans won its championship.
The discipline for the Saints' involvement in the bounty scheme is more far-reaching and harsh than what Goodell came up with in 2007, when the New England Patriots cheated by videotaping an opponent. Goodell fined the Patriots $250,000, stripped a first-round draft pick, and docked their coach, Bill Belichick, $500,000 for what was known as "Spygate."
Clearly, Goodell decided that attempts to hide the bounties were as significant a breach as the original rules violation itself.
As recently as this year, Payton said he was entirely unaware of the bounties — "a claim contradicted by others," the league said. And according to the investigation, Payton received an email before the Saints' first game in 2011 that read, "PS Greg Williams put me down for $5000 on Rogers (sic)." When Payton was shown that email by NFL investigators, he acknowledged it referred to a bounty on Rodgers, whose Packers beat the Saints in Week 1.
The league said that in addition to contributing money to the bounty fund, Williams oversaw record-keeping, determined payout amounts and recipients, and handed out envelopes with money to players. The NFL said Williams acknowledged he intentionally misled NFL investigators when first questioned in 2010, and didn't try to stop the bounties.
Vitt was aware of the bounties and, according to the league, later admitted he had "fabricated the truth" when interviewed in 2010.
Loomis knew of the bounty allegations at least by February 2010, when he was told by the league to end the practice. But the NFL said he later admitted he didn't do enough to determine if there were bounties or to try to stop them.
