I see that Ole Miss has more than a dozen players suspected of having H1N1 Flu and they are trying to isolate them. I think I read that Tulane was also dealing with this. It might be that this season the top teams will end up being those who are not only good, and stay healthy at key positions, but also avoid the Flu spreading amongst their team. Ole Miss
What about players and managers? I'm not so sure isolation will be effective. We may see some games cancelled this season for non weather reasons.
Biggest problem with isolating players is that you are contagious for 24 hours before you have symptoms. It can control but not eliminate the spread.
