The Running Back was a workhorse from the start, going for 1,129 Yards and 10 Touchdowns.  Dillon's 1,129 was the lowest Rushing totals he had until 2003, and in his rookie seasons and each year from 1999 to 2002, he was in the top ten in Rushing Yards.  Dillon peaked at 1,435 Rushing Yards in 2000, and he had three consecutive years (2000-02), where he had at least 1,500 Yards From Scrimmage.  He was also a three-time Pro Bowler for the Bengals (1999-01).

After a poor 2003 season, Dillon was traded to New England and one of his best years in football, winning a Super Bowl Ring (XXXIX) with the Patriots, which was the same season he earned his fourth and Final Pro Bowl Selection.

With the Bengals, Dillon had 9,543 Yards From Scrimmage with 50 Touchdowns.
