Sure build a new 1 Billion Dollar Stadium. Have the Bills sign a 20 year lease.
Build it in Buffalo, tear down some old crappy section of town, with ****ty houses and old buildings and make it into a entertainment and shopping complex, with restaurants accessible on all days not just game days.
Have a Buffalo Bills Hall of fame, Make it a first class arena. with a retractable Dome. Having a retractable dome allows it to be used in the winter for other things instead of just sitting empty like the Ralph. High School playoffs could be help instead of Syracuse, let those down state teams come here, instead uf us going there.
Connect the dome to a large convention hotel and parking easy access to the I-190,90, as well as having the Bus and train stops there.
Schedule concerts, conventions, etc in there and fill up the hotel, create a buzz about this team and help to rebuild Buffalo and its image.
