Good grief. This whole story has been one of the most overblown things I've ever seen.
That quote from Bowman is the only thing this entire deal is based on. From what Snitker said, it is just about how he wore his hat during an interview, when he had it kind of cocked back and to the side, solely so that people could see the logo. If you find any picture of Acuna ever playing baseball, you will see his hat on his head perfectly straight. It is a complete non-story, but people cannot wait to blast baseball for being about 'doing things the right way,' so they assume Acuna wears his hat like Fernando Rodney and the Braves are just old, white, stuck-up morons.
In short, that article is extremely dumb, as are a ton of others that have been written about it.
