All but one member of the U.S. Olympic Committee’s Board of Directors must resign.

A new board must separate the position of athlete ombudsman from the USOC paid staff, so athletes can feel their grievances, large and small, get an independent hearing.

USOC sponsors, not Congress, should lead the drive for those changes in the aftermath of a damning report about the way USOC leadership mishandled the horrific Larry Nassar sexual abuse scandal.

But the board could start the process of replacing itself at its meeting today in California.

Nassar was sentenced Jan. 24 to 40-to-175 years in prison for multiple sex crimes after some 200 of his victims courageously testified against him in court. But that testimony did not fill in all the blanks about the case.

In the months that have followed, there remained many critical and unanswered questions about how the USOC leadership had handled - and is handling - the worst and most gruesome events in the history of Olympic sports in the United States.

The answers, searingly critical of the USOC, came this week in the report issued by Ropes & Gray, the Boston-based international law firm whom the USOC Board of Directors hired to conduct an independent investigation.

The report’s evidence that USA Gymnastics and its former chief executive, Steve Penny, acted unconscionably already had been well documented.  Its evidence about the USOC’s utter failure to act was new – and even more awful than many suspected.
