Legal experts, however, say putting the 79-year-old on the stand would be an enormous risk as he fights charges he drugged and violated Andrea Constand at his suburban Philadelphia home in 2004.
Prosecutors would be able to grill the Cosby on the lurid details of his decade-old deposition testimony that jurors heard Friday, including admissions that he obtained quaaludes to give to women he wanted sex with.
Cosby didn't respond Friday when asked by The Associated Press if he would take the stand to defend himself against the charges that could put him in prison for the rest of his life.
His client, convicted child sex abuser Jerry Sandusky, had wanted to testify at his 2012 trial, but that would have allowed prosecutors to have his adopted son testify about alleged abuse during rebuttal testimony.
Testifying under oath in 2005, Cosby said he obtained several prescriptions for quaaludes in the 1970s and offered the now-banned sedatives to others, "the same as a person would say, 'Have a drink,'" according to the deposition read to the jury.
