Mawae, a former offensive lineman, is joining Arizona State's staff as an offensive analyst, the school announced Monday.
"Kevin Mawae is one of the most respected voices in football," Edwards said in a statement. "He will add a tremendous amount of credibility and knowledge to our coaching staff. I am thrilled that I get the opportunity to reunite with one of my favorite players to coach."
Mawae spent 16 seasons with the Seattle Seahawks, New York Jets, Tennessee Titans and Chicago Bears from 1994 to 2009. He played for Edwards in New York from 2001 to 2005 when the team reached the playoffs three times.
The school did not say what Mawae's exact role would be, but the former lineman said he wanted to come to Arizona State after visiting the school with his daughter, who signed a letter of intent for the Sun Devils' swimming team.
--Running back Madre London, who announced last month that he was leaving Michigan State, committed to Tennessee for his final season of eligibility in 2018, he announced on social media Sunday.
London expects to graduate from Michigan State in May.
He ran for 304 yards on 83 carries last season as a backup to LJ Scott, who is returning for his senior season.
--Kansas wide receiver Chase Harrell was arrested early Sunday morning in Lawrence, Kan., on suspicion of driving under the influence, records from the Douglas County Sherriff's Department show.
Harrell is scheduled to appear in court on March 28.
Harrell was third on the team last season with 25 catches for 221 yards and three touchdowns as a redshirt sophomore. He has 30 career receptions and five scores.
--South Carolina, which has an inexperienced group at safety, has shored up depth at that position with the addition of Rice safety J.T. Ibe over the weekend.
Ibe made nine starts last season for the Owls and had 42 tackles. He appeared in 33 career games for Rice.
He joins a South Carolina team that went 9-4 last year in coach Will Muschamp's second season. The Gamecocks, who lose both starting safeties, finished second in the SEC East at 5-3, two games behind Georgia.
