The Hawkeyes announced Thursday that Moss, who played 102 games at Iowa after redshirting one season, intends to transfer. Moss started all 35 games for Iowa last season. He ranked fifth on the team in scoring with 9.2 points per game, second with 32 steals and fourth with 62 assists.
The loss of Moss and Cook, who submitted his name to the NBA draft, will dramatically reshape Iowa's roster next season.
The Hawkeyes reached the second round of the NCAA tournament in March, rallying from 25 down against second-seeded Tennessee before losing in overtime.
