I don't think anybody claimed that uniforms should never be changed, even year to year; it's the outlandish black jerseys, special uniforms for "special" games, etc., that folks object to ... and the sentiment or appearance of overemphasizing a single game. Personally, I'm for having one home uniform and one away uniform. That way, it's truly a "uniform" ... not a non-uniform that changes almost weekly and even includes colors other than our school colors.
For what it's worth, I can't tell much difference in the Alabama uniform. About the only thing I can see is that they used to look like a plain sweatshirt, and these actually look more like a football uniform. I'd be happier if they chose a color that wasn't so near maroon though ... more toward red would be better, I think, and closer to what "crimson" really is.
