DMV native Casey Dyches, a recent graduate of Potomac High School in Oxon Hill, Maryland, has been a shining star on the basketball court this summer.

Dyches, competing on the AAU circuit for Team Takeover National, erupted for 32 points against the New York Gauchos on July 10. He converted 13-of-18 field goals and was 6-of-9 from beyond the three-point arc. He also finished with four assists, three rebounds and three steals.

"Had a great showing at Summer Live 1 vs. NY Gauchos," Dyches posted on X following his performance.

An Athletic Family Tradition

Casey Dyches, a dynamic 6-foot-2-inch guard who has committed to play college basketball at Plattsburgh State in New York, comes from a talented family of athletes and entertainers. His mother, Dionne, attended the Duke Ellington School of the Arts (Washington, DC) where she shared the same hallway with legendary R&B singer Stacy Lattisaw, known for hits such as "Let Me Be Your Angel" and "Perfect Combination" (a duet with fellow Duke Ellington School product Johnny Gill).

Dionne Dyches, who studied piano and voice, graduated from the Duke Ellington School in 1985. "I had been a pianist for many years and I played the flute," she told High School On SI in an exclusive interview.

Dionne Dyches said when the movie "Fame" starring Irene Cara was released in 1980, she was "fascinated." That fascination prompted the Prince George's County native to enroll in the Duke Ellington School.

Dionne Dyches attended Potomac High School for a short period of time before transferring to the Duke Ellington School. "I wanted to do something in the music area," she explained.

Casey Dyches attended Bishop McNamara High School (Forestville, Maryland) where he spent his freshman season before transferring to DeMatha Catholic High School (Hyattsville, Maryland) for his sophomore campaign. He spent his final two years at Potomac High School. "You kind of got to go where the best opportunity is for you," said Dionne Dyches.

Brothers Set the Standard

Casey Dyches is following in the footsteps of his two older brothers, Christian and Corey, who both played high school sports in Prince George's County, Maryland.

Christian Dyches played football and basketball at Potomac High School but only played basketball at DeMatha.

At DeMatha, Christian Dyches shared the same basketball court with future NBA star Markelle Fultz who was the top overall selection in the 2017 NBA Draft and Chase Young who was the second overall pick in the 2020 NFL Draft.

Corey Dyches spent four years playing football and basketball at Potomac High School and, during his senior year, was named First Team All-Met in both sports, becoming the first Prince George's County athlete to earn the honor in both sports since Deontay Twyman in 2006-07.

Potomac High School boys' basketball head coach Anthony Ridley described Corey Dyches as a great player with "God-gifted talent."

Ridley Reflects on the Dyches Brothers

Anthony Ridley coached Corey and Casey Dyches in high school but Christian Dyches has been part of Ridley's coaching staff at both Potomac High School and Team Takeover.

During his senior season at Potomac High School, Casey Dyches averaged 24 points per game, six rebounds, five assists and two steals for the Wolverines.

"Casey is probably the best basketball player out of the three, but Corey was the most athletic," said Ridley, a 2013 Potomac High School graduate. "It was a pleasure coaching them."

A Legacy at Potomac

Potomac High School's alumni network includes Monty Williams, a former NBA player and head coach, along with Franklin Ross, who serves as Vice President of College Personnel for the NBA's Washington Wizards.

Ronald Darby, who spent ten seasons as a cornerback in the National Football League, and former NFL cornerback Tavon Young were once teammates at Potomac High School.

"The alumni is pretty big at Potomac," said Anthony Ridley. "It's a good connection over here."

Meanwhile, Casey Dyches, who played on a youth basketball team with University of Maryland signee Baba Oladotun, finished his career at Potomac High School by helping to lead the Wolverines to an 18-6 record. In the process, the talented guard earned All-State honors. He was named First Team All-Conference and was the runner-up for Player of the Year honors after finishing as Prince George's County's third leading scorer. "He was one of the most hardest working kids I've ever met," said Anthony Ridley.
