They are ridiculous. At some point, is it within your capacity to admit that the San Antonio Spurs might actually be a better basketball team than the Dallas Mavericks right now? That the reason the Spurs beat the Mavericks has nothing to do with biased officiating and everything to do with the fact that they are the superior team in the here and now? I doubt that. I seriously doubt that.
Your argument is ridiculous because it wholly ignores the countless variables that decide games and relies on excuse-making instead.
Half the people that follow basketball that aren't Spurs fans would agree with me that the Spurs beat the Mavericks because, at the moment, the Spurs are the better basketball team.
