The Redcliffe side were ill-disciplined and disjointed in a 26-12 loss to Newcastle on Thursday.
That result followed an opening-round 16-14 defeat to South Sydney in a clash relocated south because of the threat of ex-tropical cyclone Alfred.
They'll host an improved Wests Tigers at Redcliffe in a crucial Saturday clash, the Tigers fresh off a 32-6 thrashing of Parramatta.
"I don't think concerned is the right word," 32-year-old Kaufusi said of the side's start since former assistant Woolf took over from Wayne Bennett.
"Some adversity these first two rounds ... we're changing our game (under Woolf).
"We're looking forward to being back home, with a full week of training with no interruptions."
The former Queensland State of Origin enforcer wasn't shirking responsibility for the side's ill-disciplined effort against the Knights.
His messy play-the-ball to open the game - one of three from the team - and an unnecessary penalty in attack when the score was 6-0 set the tone.
"Discipline .. that roll ball to start the game," he lamented.
"We got no momentum through that game ... there's things you look back on and could have been better at.
"You've got to look in your own backyard, myself included, and we're not looking to point the finger."
The Dolphins are likely to welcome back spark-plug Jack Bostock, last season's Dally M rookie of the year, from a knee injury to face the Tigers.
"His energy will be awesome for us," Kaufusi said of the "cheeky" winger.
