Our perception doesn't matter. If the team is feeling like they are being persecuted (whether real or perceived) is then the emotions are real for them. It is a classic use of the Thomas Theorem, loosely quotes as, "If men define a situation as real, they are real in their consequences".
Fans, media, opponents, etc. feeling/emotions are irrelevant.
The Bills may very well be jacked up after feeling like they have been jerked around, but these are mutually exclusive and can both be true at the same time. The Bills could also be flat from feeling like they could not focus on anything this week.
