It’s not because of the workload. My role at the 2016 Olympics in Rio, leading ESPN’s coverage of the U.S. men’s basketball team for “SportsCenter” and ESPN.com, made for even longer days in some ways. What gets to you in the bubble is your lack of control, combined with the long-term isolation, all exacerbated by copious regulations and restrictions. So many rules to follow. So much time alone with your thoughts. An Olympic excursion, typically bucket list territory for most sportswriters, also lasts only three or four weeks.
