Gregg Williams (born July 15, 1958) is an American football coach, and former head coach of the Buffalo Bills. Williams is known for running aggressive, attacking 4-3 schemes that put heavy pressure on opposing quarterbacks. On March 21, 2012, Williams was suspended from the NFL indefinitely as a result of his (admitted) involvement in the New Orleans Saints bounty scandal, under which bounties were paid for causing injuries that would take targeted players on opponent teams out of games.
