Chiefs coach Warren Gatland has made it a priority to find out why his side have started all four of their games so slowly this season.
While they got away with a sluggish start in wins over the Crusaders and Blues, while convincingly putting away the Sunwolves, the Chiefs couldn't escape the clutches of the Brumbies in Hamilton.
They were down 26-0 before beginning their response and while they scored two converted tries via Aaron Cruden and Anton Lienert-Brown, the Brumbies showed admirable spirit to hold out for what could be a significant win in the context of the Australian conference.
"There's no doubt we need to address why, in all four games, we haven't started as well as we'd want to," said Gatland who saw his perfect record spoiled after his return from Wales.
"So whether we need to be a little bit more pumped up coming out of the changing rooms, or whether we need to look at our warm-up and just make a couple of changes, we need to start these games a little bit better than we have been doing."
