Rhonda Tapper later adopted two other boys for whom Charles served as a role model, flying them to Oklahoma to watch him play college football.

[1] He enrolled at Baltimore City College, where he focused on basketball, before starting to play football as a junior, only after his mother asked him to join the team or get a job.

[2] He was a two-way player as a senior, finishing with 100 tackles and five sacks on defense, while also making 10 receptions for 200 yards and five touchdowns at tight end.

[4][5] In training camp he was diagnosed with a pre-existing back condition (pars defect) that had gone unnoticed since birth, which forced him to miss considerable time, including all of the preseason games and the first three weeks of the regular season.

[6] In 2017, he made his debut against the New York Giants and tallied his first career sack.

He was declared inactive in 2 games with the return of Damontre Moore from suspension.

[7] On September 1, 2018, Tapper was waived by the Cowboys and was signed to the practice squad the next day.
