Schumer and Cuomo do not want the Bills to leave on their watch. Not that they care about football, but they don't want the negative publicity. They will open the NY State checkbook if a savvy new owner who knows what he wants, knows how to deal with politicians, and squeezes them appropriately.
They probably don’t have to do much, at least for the next several years. As part of the 2012 lease agreement with the state, the Bills’ new ownership would have to pay a $400 million penalty to move the team through 2020.
