afan, this is not true- if anything, what's proven is that the majority of people who are not unhappy with a situation are usually silent. It is much more likely that if someone is displeased, he will voice that displeasure.
I can also speak as the administrator here, that I get many PMs from members who don't post, or emails from guests on this board and the overwhelming majority are not the angry, unhappy fans you think they are. They generally condemn all the negativity here, and ask us to keep things more positive.
Nobody likes losing, and before the negative posters try to spin my words and suggest I am saying that these fans are happy to support mediocrity, that's not at all the case. But there are a lot more fans who will continue their support of Bradley that you think. And as long as there is solid support of the current coach, don't expect to see a change.
