News: Williams says he's retiring from football.
Impact: The 34-year-old Williams still has a year left on his contract with Baltimore, but told the team Tuesday that he does not intend to play next year. After winning the Heisman Trophy with Texas, Williams broke into the NFL in 1999 with New Orleans. He had five 1,000-yard rushing seasons over 11 years. This season, his first in Baltimore, he ran for 444 yards and scored two TDs as a backup to Ray Rice. Williams led the NFL in 2002 with 1,853 yards rushing for Miami.

News: Williams informed the Ravens on Tuesday that he is retiring, Jason La Canfora of NFL.com reports.
Impact: Williams carried the ball 108 times for 444 yards and two touchdowns in 2011, his first and only season with the Ravens. He also added 13 catches for 83 yards. While Williams may be remembered for his strange off-the-field antics, there's no question he put together a strong career. He finished with over 10,000 rushing yards and 66 rushing touchdowns (along with eight receiving touchdowns). During the Ravens' playoff run, Williams carried the ball 12 times for 49 yards, and the team would have reportedly welcomed the 34-year-old back for 2012. However, his second retirement will likely be his last.

News: Suggs, the most dynamic player on the Ravens' staunch defense, has won the 2011 Associated Press NFL Defensive Player of the Year award.
Impact: Suggs had 70 tackles, including 14 sacks, and was a threat all over the field from his hybrid linebacker-end position. He also forced seven fumbles and had two interceptions.
