CARLTON full-back Michael Jamison has backed the Blues' young defensive unit to play a major role in driving the club to a top-eight finish this season.

A leaky defence has proved the side's achilles heel in recent years, but the 22-year-old feels the apprenticeship for those down back is almost over. 

"It's been said before, but we have had such a young backline over the last couple of years and the focus has just been on us getting games with each other and trying to get a stable back six," Jamison says.

"We did that last year, so this year I think we can really start to work on some new things with the games we've played together, and will continue to play together”.

Far from playing down the chat surrounding Carlton’s chances this season, Jamison embraces it, saying increased expectation will benefit the team.

"There has been a little bit of talk about us this off-season and we do want to make the finals. It's not just something that we're saying. We'll all be really disappointed if we don't make the top eight.

“But talk is cheap and we'll have to see what happens on the field."

Jamison is now considered one of the anchors of the Blues' backline. It's a meteoric rise for the former rookie who hadn't managed a senior game until late in a dire 2007 season for the club.

But that all changed with Brett Ratten's ascension to the top job after round 17.

"It has been a pretty parallel story for me and Ratts," he says.

"I got my first game the week after Ratts started and we had our first win together (against Collingwood in round four 2008) so I guess we have followed kind of a similar path.

"Obviously I'm very grateful to him and I am a bit of a confidence player so having that sort of backing always helps."

Such is the coach's confidence in his young full-back, Ratten recently named Jamison part of his ideal spine along with Brendan Fevola at full forward and Chris Judd in the centre.

However, being included in such stellar company has not gone to Jamison’s head.

"Pick the odd one out there!" Jamison says with a laugh.

"It makes it a lot easier when you've got the backing of the coach and he does believe in you. It allows you to just go out there and do your job."
