If there is a piece of evidence that could turn the suspension of Gregg Williams from "indefinite" to "forever" -- two words that kind of mean the same thing except that they really don't -- consider this story from Yahoo's Mike Silver: 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 has audio of the speech on his web site. Warning: There is a lot of swearing, including plenty of F-bombs.

It's graphic in more ways that just language, of course. And it could be Williams' permanent undoing.
