After a trembling Ali lit the Olympic torch in 1996 in Atlanta, Frazier was asked by a reporter what he thought about it.
"They should have thrown him in," Frazier responded.
He mellowed, though, in recent years, preferring to remember the good from his fights with Ali rather than the bad. Just before the 40th anniversary of his win over Ali earlier this year -- a day Frazier celebrated with parties in New York -- he said he no longer felt any bitterness toward Ali, who suffers from Parkinson's disease and is mostly mute.
"I forgive him," Frazier. "He's in a bad way."
