Fuller was born in Englewood, New Jersey, to Bart Fuller and Cindy Mizelle.[1][2] His mother became a touring singer when she was 17.[2] She was on tour with Luther Vandross when she found out she was pregnant with Fuller. After he was born, Fuller accompanied his mom when she would perform with Vandross, who encouraged his tour members to also bring their children along on his tour bus.[2][3]
Fuller grew up in Norwood, New Jersey,[4] and attended Northern Valley Regional High School in Old Tappan, New Jersey,[5] where he became the team's starting quarterback as a freshman.[6] He led Northern Valley to back to back state championship appearances as a junior and senior. As a senior, he passed for 2,247 yards and 20 touchdowns, and also ran for 1,326 yards and 17 touchdowns.[7] For his career, he compiled over 10,000 yards of total offense (6,148 passing, 4,589 rushing) and scored 118 touchdowns (58 passing, 60 rushing).[1]
College career
Fuller was recruited to UCLA as a quarterback. However, he was behind several players including Brett Hundley on the Bruins' depth chart.[2] Wanting to get Fuller's skills on the field, they moved him to wide receiver five games into his freshman year in 2012.[2] Playing at the slot position, Fuller had 20 receptions for 145 yards in eight games. He continued to improve, finishing with 43 catches, which ranked second on the team, for 471 yards in 2013.[1][7] He also threw a touchdown pass to Hundley against Utah.[1] As a junior in 2014, Fuller was again second in receptions, catching 59 passes for 447 yards and a touchdown.[8] He had at least four receptions in nine games, and his 93-yard touchdown against Utah was the second-longest in UCLA history.[1]
In his senior year in 2015, Fuller was moved from the slot to the outside to give him more matchups against man-to-man coverage. The Bruins also lost Hundley, who had left for the NFL, and replaced him with freshman Josh Rosen.[7] Fuller had his best game of the season against California, when he caught seven passes for a career-high 100 yards and two touchdowns.[1][2] However, he was hampered by injuries to his head and ankles that year, and his production fell to just 24 catches for 259 yards and three touchdowns.[2] He still excelled as a kick returner, ranking sixth in the Pac-12 Conference with a 24.2 yard average.[8] He finished his college career with 146 receptions for 1,322 yards and 10 touchdowns.[2]
