Cadillac Williams

In 2018, Williams became the running backs coach for the Birmingham Iron of the Alliance of American Football. However, on January 23, 2019, he was hired as Auburn's running backs coach.

Williams served as an offensive graduate assistant at the University of West Georgia in Carrollton, Georgia for the 2016 season. Williams later served as the running backs coach for the newly created IMG White football team at IMG Academy in Bradenton, Florida.

At Auburn, Williams majored in sociology. He returned to Auburn to finish the final coursework necessary for a sociology degree in December 2014.

On August 3, 2011, Williams signed with the St. Louis Rams to be the backup for Steven Jackson. In the 2011 regular season opener, Williams had 91 yards on 19 carries against the Philadelphia Eagles. Williams rushed effectively throughout the season for St. Louis, mainly in a back up capacity. He finished the year with 361 rushing yards and 4.1 yards per carry. He also scored one rushing touchdown, in the final game of the season against the San Francisco 49ers.

After Williams' turnaround 2009 Tampa Bay Buccaneers season, in which he played in all 16 games for the first time in his career, the Tampa Bay Buccaneers had high hopes for their former National Football League Rookie of the Year Award winner. However, due to the emergence of undrafted rookie sensation LeGarrette Blount, Williams found himself cemented as primarily the third down running back for the latter half of the 2010 Tampa Bay Buccaneers season. Williams was used as a passing threat on third down and finished the season with 46 receptions for 355 yards and one touchdown (a come-from-behind, game winning catch from Josh Freeman with ten seconds left in the fourth quarter on October 24, 2010 against the St. Louis Rams). Cadillac finished the 2010 NFL season with 125 rushing attempts for 437 yards and two touchdowns (one against the San Francisco 49ers and one against the Carolina Panthers), helping his team to a 10-6 record. The Buccaneers missed the 2010-11 NFL playoffs and Williams became an unrestricted free agent in 2011.

The second tear was not as severe as the first, but Williams again endured surgery and an intense period of rehab to get back on the field. He returned to game action during the 2009 preseason and was the Bucs' starting running back to open the regular season, becoming the first NFL player to return from patellar tendon tears in both knees. On December 27, Williams had his first 100-yard rushing game in two seasons for the Tampa Bay Buccaneers and finished with 823 yards, the second highest total of his NFL career.. Williams was narrowly edged for the AP 2009 Comeback Player of the Year Award by Tom Brady, finishing second with 15 votes. He rushed for 821 yards on 210 carries with a 3.9 average and four touchdowns. He also caught 29 passes for 219 yards and 3 touchdowns.

In mid-season of 2008, Williams began practicing with the team and was listed as questionable on the official injury report. In November, he was taken off the Physically Unable to Perform list and added to the active roster. He played in his first game in 14 months against Detroit. On November 30 against the Saints, he scored his first touchdown since his return. One month later, however, during the final game of the season on December 28, Williams suffered another torn patellar tendon, this time in his left knee.

In October 2007, Williams suffered a torn patellar tendon to his right knee against Carolina, which required surgery and ended his season. Doctors were doubtful he would come back to full strength after this devastating injury. Williams, however, said that he had "no doubt" that he would play in 2008.

On January 4, 2006, Williams was awarded the Associated Press NFL Offensive Rookie of the Year award. He drew 47 votes of a nationwide panel of 50 sports writers and broadcasters who cover the NFL. He beat former running mate Ronnie Brown of Miami, who received one vote. Tight end Heath Miller of Pittsburgh and offensive lineman Logan Mankins of New England also received one vote. On February 2, 2006, Williams was announced as the NFL Rookie of the Year Award winner based on the votes of over 1,000,000 visitors to NFL.com.

Williams was unable to match the success of his rookie campaign in the 2006 NFL season, as he failed to reach the 1,000 yard mark. His reduced production was attributed to poor offensive line play and an injury that nagged him all year.

Williams entered the 2005 NFL Draft and was selected with the fifth pick of the first round by the Tampa Bay Buccaneers. He signed a five-year contract with the Bucs worth $31 million, while fellow running backs who were drafted ahead of him, including former Auburn University teammate Ronnie Brown, who was drafted 2nd by the Miami Dolphins, and Cedric Benson, drafted 4th by the Chicago Bears, held out of training camp seeking much more lucrative deals.

Jeff Reynolds of Pro Football Weekly predicted Williams was the rookie most likely to have the greatest impact in the 2005 NFL season, writing that "at the Senior Bowl, Jon Gruden was salivating over this kid. He pulled him out real early. Don't think that was a coincidence. He's the offense. Gruden has set it up, Cadillac or bust".

In 2004, Williams decided to return for his senior year at Auburn. This turned out to be a wise decision as he, along with quarterback Jason Campbell, Brown and others, helped lead the Tigers to an SEC Championship and Sugar Bowl winning season, finishing with a perfect 13-0 record and a controversial #2 ranking behind the University of Southern California. Williams went on to earn All-American honors and was named to the All-SEC first team as both a running back and return specialist. He led the team in rushing for the third time with 1,165 yards on 239 carries (4.9 avg.) and scored 12 touchdowns. He finished the season with 1,718 all-purpose yards, the third highest single-season output in Auburn school history. Williams also threw one touchdown pass against Georgia. Some argue that Williams' senior year performance was not as good statistically (4.9-yard rushing average for example, the lowest in his college career) as his others because of poor blocking, while others argue that it was because defenses focused on him specifically.

In 2003, Williams was told that he would share the load at the running back position with Ronnie Brown. Brown had completed a stellar season the previous year after picking up the starting role when Williams went down with a broken ankle. However, Brown pulled a hamstring early on in the year and sat out most of the rest of the season, leaving Williams as the sole starting running back. Williams went on to have a sensational season setting an Auburn single-season record with 17 touchdowns, and gaining a career-high 1,307 yards on 241 attempts (5.4 avg.). The 2003 season was an important season for Williams because it showed that he could stay healthy and excel on the field on his own. His highlight of the season was breaking an 80-yard touchdown run on the first play of scrimmage against Alabama.

The 2002 season started out as a promising season for Williams. Unfortunately, it also ended prematurely for him when he broke his lower left fibula against Florida and missed the last six games of the season. He amassed 745 yards on 141 attempts (5.3 avg.) and 10 touchdowns in only seven games prior to the injury.

Williams moved on to Auburn University after graduating from Etowah High School in Attalla, Alabama. He got the nickname "Cadillac" from a TV sportscaster in Alabama for the style and the way he ran - he was a notch above everyone on the field, and the name stuck. He began the 2001 season as a true freshman and the #3 running back on the depth chart. In the eighth game of the season he had a break-out game against the University of Arkansas and showed his outstanding talent and versatility as a running back. After amassing 177 yards in a 42-17 loss to Arkansas, Williams was promoted to starting running back. In the next game, the annual Deep South's Oldest Rivalry contest against the University of Georgia, he led Auburn to a 24-17 victory as he amassed 167 yards on a then Auburn record 41 carries, caught four passes for 71 yards and scored two touchdowns, one of which was the game winner. (That record stood until Tre Mason had 46 carries and 304 yards against Missouri in the 2013 SEC Championship Game.) Williams was injured early in the bitter in-state rivalry game against the University of Alabama (also known as the Iron Bowl) with a broken collar bone and had to sit out the rest of the season. In his freshman season, Williams played in nine games and finished with 614 yards on 120 carries (5.1 avg.) and six touchdowns.

Carnell Lamar "Cadillac" Williams (born April 21, 1982) is an American football coach and former running back in the National Football League (NFL), currently serving as running backs coach for the Auburn Tigers football team, for whom he also played college football. He was drafted by the Tampa Bay Buccaneers in the first round of the 2005 NFL Draft and also played for the St. Louis Rams.

The first half of the season for Williams was an up and down affair. Williams rushed for 434 yards in his first three weeks, setting records as the first rookie running back to ever have three consecutive 100 yard games, and rushing for the most yards in the first three weeks of a career, a record previously held by Alan Ameche of the 1955 Baltimore Colts (now the Indianapolis Colts). Williams was also named rookie of the week for the first three weeks of the season and rookie of the month for September. His shoes and gloves from week three were subsequently retired to the Football Hall of Fame in Canton, Ohio. In week four however, Williams dealt with injuries to his ankle and arch in his right foot, causing him to miss two weeks. In the next four games he played, including the game in which he was injured, Williams only rushed for a combined 82 yards on limited carries. However, in his next four games, he averaged over 100 yards per game (408). In his rookie season, Williams tallied six 100-yard games in 14 starts, and led all rookies in total rushing yards (1,178), rookie of the week honors (3), and finished second, behind Brandon Jacobs for rushing touchdowns (6).
