We would never deign to call an Olympic sport "easy." Eating muffins is easy. Sports at least require some motion. But if you, the average non-Olympic athlete, really needed to make the Olympic team in a pinch, you would clearly choose bobsled as your "sport."
Men wearing sport coats and jeans: no. You want to be formal? Fine, wear a sport coat. You want to be casual? Fine, wear jeans. Pick one, and stand by your choice—Like A Real Man.
