In his 2002 senior season, Long helped lead Lapeer East to their first season opener win since 1995 and their first state playoff appearance since 1993. That season, the football team set a school record by posting a nine-game winning streak, which started after an October 6, 2001 loss the prior year. The team achieved its first state playoff win in its 27-year history that season. The team's 9–2 record was the best in school history, and Long was again chosen as an All-Metro League selection on both offense and defense. That season, he became the first Lapeer East player selected to the All-state Dream Team in 2002. Although he was All-State as a lineman, Long often lined up at fullback and accumulated four career touchdowns. He finished the season as the number two football prospect in the state behind Woodley according to the "Detroit News". Long led the basketball team to a second consecutive undefeated Metro League championship season, which was the first repeat league champion since 1996 and Lapeer East's first repeat championship since 1982. Long was again first-team All-Metro League, and he was selected as an honorable mention 2003 Associated Press Class A All-State basketball player. Long was again a second-team All-Metro League selection as a first baseman. Following his senior season, Long was selected to play in the 23rd annual Michigan High School All-Star Football Game on July 26 at Michigan State University.
