You have to cover up the flaws in the system.
Even their response to Tony Lewis' request for a justification was pissweak.
how TF is an "Educational review" going to solve anything, it sounds like there was something that the reffing team weren't aware of.
Were they not aware of their responsibility to watch the play?
Were they not aware that a 7 week red card offence required action on the field?
Were they not aware of the laws governing foul play and head contact?
Were they not aware that when a player is taken off the field for a HIA that they should go back and have a look at the incident that caused it?
All of these things seem pretty bloody common sense to me!
