FILE - In this Nov. 15, 1962, file photo, young heavyweight boxer Cassius Clay, who later changed his name to Muhammad Ali, points to a sign he wrote on a chalk board in his dressing room before his fight against Archie Moore in Los Angeles, predicting he'd knock Moore out in the fourth round, which he went on to do. The sign also predicts Clay will be the next champ via a knockout over Sonny Liston in eight rounds. He did it in seven rounds. Ali turns 70 on Jan. 17, 2012. (AP Photo/Harold P. Matosian, File)
