The onus tomorrow will be on the Wai-Bush forwards to do exactly that. The efficiency of their scrum and lineout play has been a major attribute all season and, if they can be similarly efficient in their protection of ball in the rucks and mauls, South Canterbury could find themselves having to exist on scraps.
One suspects Wai-Bush will look to their forwards to lead the way in an attacking sense as well. Hooker and prolific try-scorer Andrew Makalio is clearly their most dangerous runner in broken play but the likes of James Goodger, James Wall and So'otala Fa'oso'o will also relish any opportunity with the ball in hand.
For the Wai-Bush backs, tomorrow's game will be all about doing the basics well.
Looking to match their South Canterbury counterparts for attacking brilliance would be fatal, rather they need to keep mistakes to a minimum, especially on defence, and ensure their option-taking is up to scratch.
Halfback Cody Whittaker and first-five Tim Priest will bear a large part of that responsibility and how they react to that challenge could have a big say in the end result.
There is one talking point in the Wairarapa-Bush starting line-up, Rima Marurai, who was not available for the Wanganui match, being replaced by promising youngster Chris Raymond on the openside flank.
Raymond has had an outstanding debut season at Heartland level and was probably the only Wai-Bush player last weekend who had reason to be happy with his display over the full 80 minutes.
He likes to roam wider than Marurai though and the tactics for tomorrow were probably seen to suit a player of Marurai's type more.
Meanwhile, Wai-Bush Rugby Supporters Club president Roddy McKenzie says at least a dozen members will head south to Timaru for tomorrow's game and are confident of their side putting up a strong showing. "We believe they can win. Give us 80 minutes like the second 40 minutes last weekend and they'll be in the grand final."
