Handing Luatua a tough sanction will enforce the message that tackling has to be lower. And no matter Luatua's longer term fate, his Blues coach Tana Umaga isn't going to fight the system or justify his player's actions.
"It sends a message that you run the risk," Umaga said of the red card. "If you are ill-disciplined they [officials] are not going to tolerate it. We have to look at it [like this] if you can't adjust your tackling style or tackling discipline, it's not going to be good for the team.
"We can't question Steven's want to do well for this team it is just a technical thing that he needs to work on."
Reduced to 14 men, the Blues were run off their feet by 60 minutes - a forlorn and sorry Luatua left to watch on from the dug out, mulling his obvious feelings of guilt, remorse and regret.
There was no getting away from the fact his red card all but killed any chance his team had of winning and Umaga knows that he can't afford for any of his players to make the same mistake in future games.
