I have been one of those demanding that our front row is selected on scrummaging ability But I also expect that they will use the same basic physical skills you need for scrums to hit rucks and move bodies and make tackles in close.
I do not expect our front row to run 60 metres and score in the corner. I also don't expect that they will do scything covering tackles on wingers. We have other players to do that. What I do expect is that in 50 minutes they will hit 20 rucks and make 10 good tackles, missing no more than one. Only Slipper and TPN are even close to that and neither can get a run on spot. None of the other front rowers selected are within cooee of making those KPI's.
More than any other improvement across the team, more than any fiddling with the backline, dropping the Pooper (why not drop both since we can't decide which one?), dropping Mumm and replacing him with our particular favorite, getting the front row to do a good day's work would make the most improvement in our rotten results this year.
