With the likes of Paul O'Connell, Donnacha Ryan, Ian Nagle and Dave Foley also available at lock, Munster are not short of second-row options.
This meant that last season Holland was mainly seen in the back row, but he admits he is happy to feature anywhere at Thomond Park.
"Listen, to get anywhere, with the squad we have here, whether you're four, five, six or eight, anywhere in the pack you'll take the person's hand off for it (the jersey)," he said.
"There's such a good squad here. And that's hopefully what will drive us on during the year, is that lots of people will get opportunities.
"So whether it's the second row or the back row, I'm just very keen to make the most of it.
"There is a bit more effort required in the second row in terms of pushing but the way the game is going, it doesn't matter to me what position I'm playing."
Holland and O'Callaghan staying in the second-row isn't the only thing to stay the same in Rob Penney's second RaboDirect PRO12 game.
Penney has made just two changes with Stephen Archer getting the nod ahead of BJ Botha in the front row while Dave O'Callaghan is given the No.6 jersey over Paddy Butler.
Treviso travel to Ireland full of confidence after beating champions Ospreys 12-6 in round one, but despite this Franco Smith has rung the changes.
Brendan Williams has been named at full-back in place of Kris Burton, who drops to the bench, while Luca Morisi comes in at centre, meaning Luke McLean drops out of the 22.
Up front Michele Rizzo and Lorenzo Cittadini come in at prop, Valerio Bernabò and Antonio Pavanello come in at lock while Paul Derbyshire and Dean Budd earn a run in the back-row.
And although they have already put the defending champions to the sword, Corniel Van Zyl insists nobody at Treviso is getting carried away,
"We will take the win against Ospreys, it is a long season and there are a lot of games ahead of us so we won't get ahead of ourselves and start thinking differently," he said.
"We will just focus on the next job in hand and that is against Munster. The boys aren't going to get carried away.
"It will be harder this weekend playing away so we've got to put in a great performance, that will be the main thing to focus on instead."
At Thomond Park, 8pm.
