All three transfers are post players. Mitchell is a 6-8, 260-pound forward transferring from Maryland, Cox is a 6-8, 276-pound center transferring from Mississippi and Jacobs is a 6-8, 245-pound forward transferring from Alabama.
“We’re excited to have Demarco, Nick and Charles join our program,” Gregory said in a release. “They have all proven themselves at this level, and all three of them fit in well with our program. They’re all excited to be here.”
Mitchell, a former standout at Wheeler High School, intends to request a waiver from the NCAA for immediate eligibility in 2014-15, the release said.
He averaged 6.0 points and 5.8 rebounds over 70 games, including 17 starts, in two seasons at Maryland. Last season, Mitchell averaged 6.5 points and a team-high 6.3 rebounds over 32 games, and started the final 10 games for the Terps.
Mitchell is the third Cobb County product to transfer to Georgia Tech since 2010.
Whitefield Academy’s Brandon Reed came to the Yellow Jackets after a season at Arkansas State, then went back to his original team as a senior last season. McEachern’s Trae Golden spent his final year of eligibility with the Yellow Jackets last season, after three years at Tennessee.
Cox, from Yazoo City, Miss., is expected to graduate from Ole Miss this summer, enroll at Tech for the fall semester and be immediately eligible to play for Georgia Tech in 2014-15 as a fifth-year graduate transfer.
Cox played 33 games and started 16 for the Rebels in 2013-14, averaging 4.2 points and 4.9 rebounds in 16.6 minutes per game. He shot 54.3 percent from the floor and blocked 25 shots.
Jacobs, an Atlanta native who attended South Atlanta High School with former Georgia Tech star Derrick Favors, will sit out the 2014-15 season and play his final year in 2015-16.
Jacons averaged 8.4 points and 3.5 rebounds for Alabama in 2013-14 in 25 games, making 10 starts. In three seasons, Jacobs played in 93 games and made 57 starts for the Crimson Tide, averaging 7.3 points and 3.4 rebounds per game.
Georgia Tech also announced Tuesday that sophomore guard Josh Heath, who transferred from South Florida following the 2013-14 school year, will be able to play for the Yellow Jackets in 2014-15 after having his eligibility waiver approved by the NCAA.
Heath’s father, Stan, was fired as South Florida’s coach following the season.
Josh Heath, who will have three years of eligibility, played in 17 games for the Bulls last season, starting the last four.
