Stalk, one thing I have noticed over all my years is that generally speaking, referees are predisposed to thinking that the predominantly black team is undisciplined, while the predominantly white team is well-coached. West Catholic has had some terrific teams over the last decade. I mean really terrific. Yet, nearly every time they are on the short end of the stick when it comes to judgement penalties (personal fouls, holding, illegal blocks, pass interferences) in big games. And trust me, but I'd be the first one to tell you that they have had their bouts with remaining focused and discipline. And I'm not talking about obvious penalties that the entire stadium could call; like offsides, delays, face masks, etc. I'm talking about the judgement calls. A couple of years ago I had the data to support this theory. It was staggering.
Not pointing at one referee, or one crew, or one district, but from a general sense I think this belief has some validity to it. I'm sure this will upset some, but oh well.
Unfortunately, what we have here is probably just a microcosm of what perceptions are in society. Not good.
