I suspect that Flood knew that some of his players were involved in something back when it happened.
@rucoe89's post is not an unlikely scenario. The players may have told him some of it, the cops some of it. But I don't think he had the full picture until today.
In the meantime, what's he supposed to do? If the players are telling him "we didn't do it" and the cops are not providing definitive answers either, then I don't see that he has much choice except to forge ahead the best he can without all the facts.
And although I accept that we're living in the brave new reality-TV, 24/7 media world where everybody thinks they have a right to know every intimate detail about everyone else, I'm resistant to that trend. If Flood
did have some limited knowledge of the situation, I applaud him for keeping his mouth shut about the situation until such time as he had enough facts to start forming reasonable conclusions - which pretty obviously was sometime earlier today.
And let's not forget that some of the players involved may turn out to be innocent of the charges for which they were arrested. Not saying it's likely, but it's possible.
