Dumb enough that defensive coordinator Gregg Williams instructed his players to injure 49er players on tape. Yahoo! Sports:

The night before Gregg Williams’ final game as the New Orleans Saints’ defensive coordinator, the since-suspended coach gave a fiery speech to the team’s defensive players during which he made specific references to inflicting physical punishment upon several San Francisco 49ers in a postseason game the next day.
In the speech at the team’s hotel near the San Francisco Airport, Williams – according to documentary filmmaker Sean Pamphilon – at one point made a hand signal suggesting he would personally pay for a ferocious shot on 49ers quarterback Alex Smith.
Williams also referenced the prospect of his players inflicting a severe knee injury upon San Francisco wideout Michael Crabtree and exhorted them to “put a lick on” backup receiver Kyle Williams in an effort to “find out” if he was still suffering from the effects of a late-December concussion.
Williams’ speech, delivered less than two months before the Saints’ bounty scandal became public, was revealed to Yahoo! Sports by Pamphilon, who had access to various team functions for much of the 2011 season.

Pamphilon, who directed the critically acclaimed “Run Ricky Run” documentary for ESPN, is working on a project featuring former Saints special teams ace Steve Gleason, who is suffering from ALS. Pamphilon has released an audio recording of the profanity-laced speech (also obtained and listened to by Yahoo! Sports) on his website and said he believes “there’s no doubt at all” that Williams put a bounty on Smith in the meeting.
