Kathleen Kennedy, Quarterback Princess?

Was Lucasfilm CEO's football claim inspired by the 1983 Helen Hunt made-for-TV film?

Recently, I wrote an essay about Kathleen Kennedy that went viral, so I followed it up by looking for further information about her. That’s how I found out that Vanity Fair and kids’ lit publisher Bellwether Media have propagated a dubious anecdote that Kennedy was the quarterback of her middle school boys’ football team.
