So the prevailing, and most acceptable, stance is to ignore the poor play and hope things improve? Is that what you do when your child's school is lousy, when your mechanic screws you over, when you plumber's bill exceeds the estimate by 30%?
The definition of fan is not synonymous with blind allegiance. A fan is knowledgable, aware, focused and doles out both constructive and critical comments as she or he sees fit. The Bills suck, they have sucked, they will suck for the foreseeable future; that's the real world right now.
