50000 is 13000 below the smallest current NFL stadium
Also, the sight lines of the skydome were created for baseball primarily and anyone who's watched a football game in a stadium not designed for it will tell you that you can get some real awkward views in a stadium like that. the KingDome in seattle was famous for this.
That is why a new stadium is necessary.
As for buyers, no one has really expressed interest one way or the other have they? Golisano is the only one who said anything thus far about making the purchase and truthfully I would prefer him not buy it because I think he would be just as bad as Wilson as the owner.
So right now from the looks of it, it will be a time consuming process even after Wilson dies, which could very well be this evening, before any type of move is made. But the numbers speak for themselves, to move the team from Buffalo is going to cost a substantial amount of money and still require League/Owners group approval before anything happens. On top of that, there are other teams in just as bad of shape financially. Personally, I see Jacksonville and the Bay area teams as the top contenders for a move along with the Bills. And don't leave out Minnesota, they are the lowest valued team in the league and could really use a new stadium as well.
So like I said, find some real info to support your thesis rather than the old run of the mill crap that gets cycled all over the net and you might get some people to really listen.
