There actually isn’t a rule against stealing signs. I think Houston has been punished enough. They lose their gm who orchestrated one of the best statistical teams in baseball history (not hyperbole) they lose the head coach who managed these stars egos so well, was fined six million dollars and lose first and second round draft picks for the next two seasons.
Really if baseball wants to get rid of sign stealing skip the signs Altogether and have a mic like the nfl has
