I think people need to give the Chiefs some more credit rather than chalking that up to just the Brumbies being woeful, not that I'm going to argue that, that was their best performance.
The Chiefs just outplayed them in almost every part of that game. A real class performance and sets a good gauge of where the top is at. Toole's pace aside I'm not sure that the Brumbies had an answer of how to unlock them and never looked like they were going to find their way back into that game (Bernie's comments after halftime gave a pretty good indication that he could see that they were being outclassed and off the pace).
Fundamentally the Brumbies lost that at the breakdown with the Chiefs just getting fast front foot ball all game, whilst doing a good job of nullifying the Brumbies who were often behind the gain-line or working off slow ball. There wasn't really any tricky plays or innovative patterns from the Chiefs, just lots of the basics down well, at pace, again and again with players backing up. Beyond that you could see they had a plan to test the Brumbies backs with those highballs that they kept peppering them with, particularly Toole's side of the field.
I agree with
@Tomikin's assessment of some of the players. Sapsford in particular looked really off the standard. I think it's hard to have a go at the backs too much however with the forwards hardly setting the platform.
Such a shame that it wasn't more competitive after all the games so far this weekend.
