"That's a longer term strategy for a team whose home city could change when the team owner passes, which could happen two seconds from now."
The likelihood of the Bills leaving the Buffalo area any timethis decade is approximately zero. Consider this;
1)You need a regional fan base that can consistently draw over 70,000 people to attend any game being played by a reasonably compettive team. Either one market with over 2 million population base, or two or more markets each with over a million metro population within 65 miles of the stadium, will get you there.
2) You need a stadium able to accomodate all those 70,000 people that team draws each game, and it needs luxury seats and boxes to go with it, plus adequate parking and highway access.
3) You need enough decent size media markets within a 90 minute drive of the stadium to offer a good network with revenue potential, or one BIG market at the heart of the team's fan base.
There are roughly 36 North American markets that coukd conceivably support an NFL franchise under these criteria,, including Buffalo. What about the four others? Let's look at why each of them don't, and can't, pose a threat to take on a team like the Bills even if the Bills want to move...
1)Portland, Oregon; No suitable stadium with seating capacity and luxury boxes, and none in the works.
2)Los Angeles; lack of a suitable facility, like Portland, plus a record of past failure to support not just one, but two different NFL franchises in the past 20 years.
3)Toronto; No stadium able to come within 25,000 seats of the Ralph, plus lukewarm fan response to the one or two games a year the Bills DO play there at the under-sized (for the NFL) Rogers Center.
4)San Antonio; a market with some potential, but its biggest stadium (the Alamo Dome) has only HALF the seating capacity of the Ralph.
So there's no realistic place the franchise can move at any time this decade. If you take on the Bolls as a broadcast partner you can expect them to stay put.
