Edwards, who played and coached in the NFL, was a big reason the Bowie 2019 receiver/defensive back picked the Sun Devils.
"Both the defensive and offensive coaches have developed a relationship with me," the 3-star prospect said. "The meeting with Jean Boyd and Alonzo Jones blew me away."
Edwards played 10 seasons in the NFL and later held head coaching stints with the New York Jets and Kansas City Chiefs. He was also the defensive backs coach at San Jose State from 1987-89. Edwards was an analyst for ESPN during the previous nine years.
Arizona State will be his first head coaching job in college.
"Getting coached by Herm Edwards seals the deal," DeArman said.
DeArman held 27 offers, according to 247Sports, and made an official visit to ASU on June 1.
"I felt extremely comfortable during the visit," DeArman said.
He also considered Wisconsin, Arkansas, Baylor, Texas Tech, Utah, Washington State and San Diego State.
DeArman recorded 990 total yards, six touchdowns, 64 tackles, three interceptions, four pass deflections and two forced fumbles in 2017.
He's the No. 90 ranked athlete in the nation and No. 130 overall player in the state.
