A hallmark of Rennie's teams is the way they keep things simple. Take the 20-year-old prop Ben Tameifuna who was making his Super Rugby debut against the Blues. I thought he did quite well and that's because all he was asked to do was push in the scrums and lift in the lineout.
He was able to keep the scrum steady. The ball came out well enough so there was an opportunity for the backs to do something with it. And that's all that was required. The Chiefs just needed to make sure they were physical enough to provide some kind of platform at the set-piece and then mobile enough to get to the tackled ball and protect possession.
It was the same with big lock Brodie Retallick. I know a wee bit about Brodie because he was at Christchurch Boys' High School and I saw him play First XV on a few occasions. He looked like a boy in a man's body back then and he has come a long way since he left school.
Again, he's been asked to scrummage, win a few lineouts, hit a few rucks and carry a couple of times a game if he can. Nothing too demanding - just good execution of the core skills that will help build enough of a platform.
When you look at the talent in their backline, the Chiefs tight five don't need to be dominant. If they can provide 45 per cent or maybe even 40 per cent of possession, then they will be competitive. With Sonny Bill Williams and Richard Kahui, as well as Tawera Kerr-Barlow who was excellent and Tim Nanai-Williams, the capability is there for the Chiefs to score from limited rations.
These guys are exceptionally talented footballers as they showed on Friday night and there was a lot of confidence and belief in the way they played.
Rennie is a smart coach and he won't look for the Chiefs to build more elements into their game just yet - his focus will be trying to sharpen and improve the execution of those basic skills.
