As far as not punishing innocent people, in this case the players and new coaches... Don't most punishments in some way indirectly punish innocent parties?
Example: A guy goes to prison for whatever reason, well didn't his 5 year old innocent boy just lose a father? Didn't his innocent wife just lose a source of income?
Another Example: A guy just getting by on mimimum wage gets a $100 traffic ticket and the points on his license increase the cost of his Auto-Insurance. His innocent kid now has to get less Christmas gifts.
Final Example: After 9-11, students could no longer go in on a weekday into the stadium and run around on the field and up the stands for exercise. On game days a whole list of seemingly harmless items were banned.
Maybe poor examples, but it seems like one could argue that innocent people are commonly indirectly hit by the punishments of the guilty.
I am not sure what the penalty should be, but maybe a loud message needs to be sent whether or not innocent people are influenced. But, I would prefer to not drastically effect players there.
We do punish to reform the offender and to prevent others from doing it. Maybe the punsihment needs to be severe to prevent others from looking the other way again.
