Seems obvious to me...
If the administration gives the fans the finger by keeping Flood, a good portion of the fans will give the finger right back and say the hell with this. How many is debatable, but no doubt, it will happen to some extent.
The difficult thing to estimate how much lost revenue there will be from lost donations if we keep Flood.
There are probably a lot of people on this board (and elsewhere) that will make a one time donation if we hire a new coach, regardless of who it is.
My guess is the better received the new coach is, the more $ people will donate to help our financial situation and support the football program.
If we hire a perceived dud, the contribution will be small.
If we hire a perceived home run, the contribution will be greater, as the fans will reward an effort by the admin to put the best product possible on the field.
If we keep Flood, (almost) NO ONE (there are always some wacko exceptions) is going to increase their donations.
This is probably not a typical example, but I will admit I have given very little to the athletic department in my lifetime.
If we get rid of Flood, I will make a donation (however modest).
If we don't, I wouldn't even consider giving a penny because I feel like it would be giving my approval (and $) to Flood.
