What I'm not sure any of us know is the degree to which the incumbent owner's wishes count in selecting from prospective ownership groups. After all, the team is technically the property of one man, not a Committee of NFL owners.
For all we know, Mr. Wilson, who knows the process and personalities better than anyone, may place stipluations on the sale to favor an ownership group that is committed to keeping the team in Buffalo. Hypothetically, this stipulation could be made with a requirement that the winning bid (for an owner committed to Buffalo) be no less than X% lower than the team's full open market valuation, or X% lower than the highest valid bid.
If such a stipulation from Mr. Wilson carries any weight with the other owners (and I suspect it would if he took the trouble of crafting it, given his Hall of Fame credentials), this Fund could be relevant.
