If your star player violates those rules, why should he be exempt? I don't really know how strict the Yankees are about their no-facial hair rule, but let's say they are procrustean, and Robinson Cano grows a beard, the reasons for which are nobody's business but his own. Shouldn't "rules are rules" be applied in this situation?
No big deal. I just wonder if we sometimes speak with forked tongues.
As for uniforms, what if the brass says you've got to wear your pants/socks/stirrups the old-fashioned way, and you choose not to. Suspension?
