USC's DeMar Derozan, Taj Gibson and Daniel Hackett have decided to enter their names into the NBA draft, sources said.
Hackett will hire an agent, according to a source familiar with the Trojans program, making him ineligible to return to USC.
Derozan and Gibson will not initially hire an agent, leaving the door open for a possible return.
"He's torn between going into the draft and staying at USC," DeRozan's father said. "He wants to stay, but his mom is real sick."
