Carrazzo took over as Blues vice-captain ahead of last season, but managed just 10 games as he struggled with a persistent calf injury.
Unable to set the on-field example he would have liked in his new role, Carrazzo became extremely frustrated.
"I think in the past I've been OK with being injured – not OK but I've been able to deal with it OK – but it was a real battle last year," Carrazzo said on Wednesday ahead of Carlton training at Visy Park.
"It was my first year as vice-captain of the club and I really felt a responsibility to the group to be out there helping them as much as I could and that was disappointing from that respect."
Fortunately, Carrazzo is confident his calf problems are now behind him. After post-season surgery, he has been in full training since the start of December and expects to be fully fit for the start of the 2014 season.
Marc Murphy also entered his first year as captain in 2013 as the Blues ushered in a new leadership team following Chris Judd's decision to step down as skipper after five years.
Like Carrazzo, Murphy endured a tough first season in the job, struggling to have his usual influence in the midfield after a limited pre-season and then coming under greater attention from opposition taggers.
But Carrazzo said Murphy had noticeably grown as a captain during his second pre-season in charge.
"Vocally he's definitely stepped up. He's taken more control of the group," Carrazzo said.
"He's sort of measuring the mood of the group and how everyone's going, so I've definitely seen a step up in that regard from Murph.
"I'm expecting him to take control of the group and have a big say in where we go."
Carrazzo said Nick Duigan's surprise retirement in December because of a chronic knee injury had been disappointing, but praised the AFL latecomer's contribution to Carlton over three years and 43 games.
"Nick was a big part of the group and he's just a fantastic guy and a really positive guy to have around the group, so [his retirement] was really disappointing.
"But unfortunately that's the nature of the game … sometimes injuries can pull you down and put an end to your career.
"But I think if Nick looks back on what he's been able to achieve and how late he was coming into the game and the impact he was able to have on the club, it's been great – a real credit to him."
