During the McDermott era, the Bills have generally dominated inferior opponents at home. The Raiders are an inferior opponent, the Bills will win in dominating fashion. The vast majority of people, including me, will be enjoying the win on Sunday. This will be the first win of 11 of 13 regular season wins.
During the following week, there will be discussions comparing and contrasting the week 1 loss and the week 2 win, trying to parse out what are the "Real Bills". After 1000 threads and 100k posts during the regular season related to that discussion, it will still remain to be seen in the post season who the "Real Bills" are.
