When did they announce that plan?
The only credible indications have been that Wilson's surviving family will be unable/unwilling to pay the estate taxes necessary for them to obtain possession of the team.
In 2010, John Wawrow said "From what I've heard in the background, and seen happening - without saying anything definitively, because I can't, because no one's actually told me anything - I have a better feeling that this team might be here longer, beyond Ralph Wilson, for a long time,"
This vague statement is the most credible report of what may happen when Mr. Wilson no longer owns the Bills. Very few people know the plan. The people who do know are not talking. People close to 'the people who know' do not seem as worried about a Bills move as they were 10 years ago.
