The Bills, in their entire history, have had a single 9 home game season (2021). No it's a tragedy that they will lose one next year? No. Disadvantage? In 2021, half of their losses came at home--even with the extra game.
Anyway, international games have existed for some time now. I missed your posts of all those other teams losing a home game, paying for a plane etc. Or is this a new concern for you? 5 AFC teams will play overseas next season.
Schedule all games as away games for all teams? Well....it would have to be a home game for the team that's not the away team.
why does it suck? Who's we? You can simply turn on your TV and watch it as always. If it sucks don't watch.
