I am not familiar with the official baseball rules- can someone (a Blue would be great!) point out where the rules prohibit stealing signs? Honestly, i dont know what the rules are on this but i know i am like one of the only coaches i know who does not do this.
The rule book specifies that the use of mechanical methods of stealing signs is illegal and the league office has made some provisions to make electronic sign stealing illegal as well, although it's not in the rule book officially that I know of. Doing it the old-fashioned way isn't against the rules, written or otherwise.
is stealing signs like When one college softball pitcher is allowed to leap and replant her way to championships and awards? even though Everyone knows there are rules against it and penalties dictated, but its still allowed?
If you're asking if ruling bodies for sports all turn a blind eye to rule breaking when it's convenient and helps the brand make money? Yes, it's exactly the same.
