Explain to me why Brian Williams (a respected journalist and newscaster at the time) told and retold the story about how the chopper he was on was forced down by enemy fire or Hillary Clinton (a favourite to win the Presidency at the time) telling a story of dodging sniper fire in Bosnia when she was filmed being greeted on the tarmac with flowers.
Because people don't invent stories? It's really bizarre that you believe this.
Exaggerating a story about yourself (basically resume-padding) is not the same thing as inventing stories about others. And one of the people you're listing isn't even a media member.
The fact that someone somewhere once lied about something doesn't mean that there is an epidemic of people in the local sports media acting like total sociopaths and inventing stories.
Like, when a report doesn't appear to be true, these are the options :
1) Reporter believed they were reporting something correct but there was a breakdown in the chain of information.
2) Story is true but the parties involved have done a good job issuing a denial.
3) REPORTER IS A SOCIOPATH INVENTING AND PUBLISHING NONSENSE THAT THEY MADE UP!
It's absolutely f***ing insane that people default to (3) instead of the much more obvious and logical alternatives.
