Those MLB guys have millions on the line, and it looks like they still can't keep from getting infected and then passing along the infection to their teammates. It's hard to imagine amateur athletes--young, high-testosterone college kids--being able to resist all the temptations of living alone at 18-22 years of age, while taking classes, etc., enough to avoid infections. All it takes is one guy to go out partying with friends, infect half the team over the next two weeks, and then that team is out of commission.

This happens two or three times in any given conference, and it's likely the whole conference crashes and burns.
