Division II Angelo State (Texas) unveiled new black uniforms on Monday, and decided the best way to reveal those new uniforms to the team was to assemble them on the field, and then have someone drive to them on a motorcycle, rip off a trench coat, and stand there in his black and blue glory. Like an extremely scaled down version of Batman or something.
Angelo State, nicknamed the Rams, usually goes with a knockoff of the St. Louis Rams for its visual presentation.
A black alternate makes sense, if only because it's 2014 and seemingly everyone needs a black alternate, but pairing black with yellow would contrast much more effectively than blue on black.
