Dozier was born in Norfolk, Virginia. He attended Kempsville High School in Virginia Beach, Virginia, and later attended Penn State University. When D.J. was 12 years old, he played on a youth basketball team for Kempsville and made it to the Virginia Beach city championship game. His team played against the Green Run Suns, who had future NBA Hall of Fame player David Robinson on the team. Kempsville won the game, mainly in part to David Robinson (who was a small forward and not the tallest player on the team nor highest scorer) missing the game due to having come down with the mumps. Dozier, who would eventually grow to 6 feet tall, was already 5'9" or 5'10" by 12 years old. With his athleticism, skill and size, he dominated the undefeated Suns and won the city championship.
He had a career average of 4.0 yards per carry. In 1991—his final season—he averaged 5.3 yards per rush.
He fumbled the ball only 4 times during his 5-year professional career.
Dozier had a perfect 158.3 passer rating as a pro. (He was 1-for-1 for 19 yards and a touchdown)
Dozier caught 33 career passes, averaging 9.1 yards per catch.
As a kick returner, he averaged 19.4 yards per return.
