The Blues went down to the Brisbane Lions by 19 points after leading by seven points at the final change.

Jamison, who had the job of marking Brendan Fevola, was clearly frustrated by his team's inability to kick accurately for goal and to deliver with precision into the forward line.

"I don't think we can knock our effort," Jamison said.

"All our indicators said we won the ball inside and our pressure was pretty good.

"It's more probably our execution in the end, we missed too many goals early that we should have kicked and we were pretty sloppy over the ground by hand and by foot."

Its dominant third term may have sapped Carlton's energy, but Jamison would not use it as an excuse - pointing to a seven-day break compared to the Lions' five days.

"I think we overused it by hand and over-finessed it and our tackle pressure probably went down a little bit as well so we've only got ourselves to blame," Jamison said.

Jamison held Fevola to 3.3 for the match, keeping him goalless for the second half.

But he said the Lions cast of forwards, including Jonathan Brown (seven goals), Todd Banfield (two) and Brent Staker had too much room to move.

"[We're] going to cause trouble when we're playing well and using the ball well," Jamison said.

"But when you turn it over and give them a lot of space in the forward line to roam around and do their thing, it's pretty dangerous."

Jamison avoided harassing Fevola during the game and felt that the Blues' forward line was coping just fine without their former teammate, although Eddie Betts and Chris Yarran failed to kick a goal between them.

He said the mixture of small and tall players could make for a potent combination.

"Hopefully when things are going well we've got Eddie Betts and Chris Yarran running around causing danger, and Lachie Henderson and Setanta O'hAilpin both played really well as those tall forwards," Jamison said.

"When they're all up and going at the same time they'll be pretty hard to match up on."
