The rules are stupid because the rule has been brought in without thinking the repercussions though. Since teams who reach the maximum rotations allowed will be forced to keep injured players on the ground until the end of the quarter? What are the penalties for exceeding the maximum, what are the legal repercussions for clubs that do not allow injured players to come off the field? The blood rule forces players off the field. The rules are changed by reactionaries not thinkers.
