A new forward-line structure has been installed, while a harder, more defensive game plan all over the ground has also been implemented.
Speaking on Monday, Carrazzo, who is about to play his 100th AFL game, wasn't promising miracles but said belief within the playing group was strong ahead of the clash against Richmond.
"Obviously it's something that we haven't got 100 per cent down pat yet - I don't think any team really has - but it's going to be a big test for us to see if we can lock that stuff down," Carrazzo said from Visy Park.
"If we can then we're a big chance to win more games than we lose.
"[But] we're very confident - we train that sort of stuff up every time we're on the track - and sometimes the best test is against yourself."
Carlton will go into battle without former spearhead Brendan Fevola and will have to deal with the added burden of doing so without skipper Chris Judd who is serving the first week of his three-match suspension.
"It will probably have a bit of an impact but we've got Brock McLean in this time and Lachie Henderson [and] other guys like Eddie Betts, Mitch Robinson and Ryan Houlihan are in much better condition than they were this time last year," Carrazzo said.
"If anything I think we're in a stronger position than we were in round one last year.
"Fev came in carrying an injury and didn't really play that well, so if you look at it from that perspective, I think we're in better condition physically than we were this time last year."
The Blues handed the Tigers a thrashing in the corresponding fixture to open last season from which the Tigers never fully recovered. Carrazzo expects a fierce opening as a result, but he doubts a loss to either side could have a similar effect this year.
"Once the season's over and they had a poor [one] you can probably draw the connection, but it doesn't mean that the season's over if we lose in the first round," he said.
"We can expect that they're going to come out flat-out at the start, but they're probably expecting us to do the same. It's probably who can hold that intensity the longest will win."
The 2007 John Nicholls medallist is delighted to be within reach of a goal that appeared unlikely when he was made a rookie by the Blues after an unsuccessful stint on Geelong's rookie list.
"When I first started, 100 games seemed a million miles away, but in the last few years as it's got closer I thought it would be a good achievement to get," he said, adding his humble beginnings continue to serve him well even today.
"I still feel an element now of having to prove myself and battle a bit, but that's just the nature of things. Early on it was definitely trying to fight tooth and nail to hold my spot, but it's not a bad way to play footy - being in that survival mode.
"I've never lacked confidence and I don't think I ever will, but it's just a case of feeling like I've got to constantly prove myself whether it's to myself or to reach my goals or whatever - it's just the way I am mentally."
