Coachwear is really an underexplored and underappreciated aspect of the whole sporting experience. And I say this as someone who is generally pretty ignorant of fashion in general (as my five total pairs of t-shirts and single polo shirt that I got for Christmas eight years ago will attest), but it's weird and kind of fascinating how much time and effort we put into decoding the messages and intent behind what the coaches of our favorite sports teams wear on a regular basis.
This hits across virtually every sport, because all of them have some kind of weird code or standard for what's acceptable or expected for coaches to wear, even though we live in the year two thousand and eighteen, so presumably at this point in the plot we should've all given up our clothes for monochromatic unitards with different lapel pins that designate which part of the spaceship we work in.
