OSAKA -- The head of the U.S. Olympians Association said here Wednesday that he is satisfied with International Olympic Committee President Jacques Rogge, but added it is still too early to tell whether the IOC will reform itself.

Speaking at Osaka City University, John Naber said that Rogge, who replaced longtime IOC head Juan Antonio Samaranch last July, impressed him at the Salt Lake City Olympics in February.

Naber, who won four gold medals in swimming at the 1976 Olympics in Montreal and later became a critic of the IOC's lack of public accountability, was visiting the city at the invitation of the Osaka Municipal Government. He now works as a motivational speaker in Pasadena, Calif.
