GEELONG and Collingwood are now the only undefeated teams in the competition, but Cats coach Chris Scott continues to play down the achievements of his side.

Scott's men won their third straight match when they thrashed Port Adelaide by 79 points at Skilled Stadium on Sunday.

"The fact that we've won three games doesn't really tell the footy world much … except that we're not completely hopeless," Scott said at his post-match press conference.

"We do have some testing times ahead. We play a very good side [the Sydney Swans] at the SCG next week and we play a very good side [Hawthorn] at the MCG the week after.

"The next fortnight will tell everyone a bit. But it's not until we're half-way or three quarters of the way through the season that we'll know exactly who sits where in the competition."

The Cats have to wait until round nine to take on Collingwood. When that clash comes around they won't want to start like they did against Port Adelaide.

They had only four tackles in the opening quarter, a statistic that certainly riled their new coach.

"We were disappointed," Scott said. "We really pride ourselves on getting in and winning the ball first.

"We knew they would come out hard early, and they defend really aggressively.

"So from that perspective we expected it to be a bit of an arm wrestle, but they were just beating us in at the ball and we couldn't get hold of them in the tackles.

"To be honest, the first 15 minutes was a real concern, but after that they really stood up."

Geelong had controlled the remainder of the game. The inside-50 count, which was 61 to 22 in the Cats' favour after quarter-time, told the story.

The home side was even able to experiment by subbing off defender Harry Taylor and sending usual forward Cameron Mooney down to the backline.

"[Harry] just wasn't feeling great today," Scott said. "We just took the chance to play Moons back and to give him a little bit of a spell. We expect him to be fine for next week."
