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.
Williams was also named rookie of the week for the first three weeks of the season and rookie of the month for September.
1982
Carnell Lamar "Cadillac" Williams (born April 21, 1982) is an American football coach and former running back who is the running backs coach for the Las Vegas Raiders of the National Football League (NFL).
2001
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.
2002
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.
2003
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.
2004
Williams played college football at Auburn, where he set the school's record for career rushing touchdowns and helped the team go undefeated in 2004, when he was named a first-team All-American.
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.
Williams finished his collegiate career with 3,831 yards on 741 attempts (5.2 yards per attempt) and 45 touchdowns, breaking the all-time Auburn career records of most rushing attempts by Joe Cribbs (657), and most touchdowns by Bo Jackson (43), while finishing second in total rushing yards in a career behind Bo Jackson.
His career total of 5,033 all-purpose yards also ranks second in school history behind James Brooks.
Williams also has the distinction of earning nine SEC Player of the Week honors in his career, the most in conference history.
At Auburn, Williams majored in sociology.
2005
During the 2005 NFL Draft, Williams was selected by the Tampa Bay Buccaneers in the first round and also played for the St. Louis Rams.
In 2005, Williams won the NFL Offensive Rookie of the Year award.
Williams attended 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.
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 worth $31 million.
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".
The first half of the season for Williams was an up and down affair.
2013
(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.
2014
He returned to Auburn to finish the final coursework necessary for a sociology degree in December 2014.
