The Crows, who watched their top four hopes slip away during the round 22 clash between St Kilda and Essendon last season, will decide their own finals fate at Docklands this week.
A win over the Blues would secure an elimination final at AAMI Stadium, while a loss could see the side head as far as Brisbane for the first week of finals.
“It’s good [to know] that if we put in a good performance, we’re guaranteed a home final the next week,” Porplyzia said on Monday.
“To make sure we put ourselves in the best position to play good finals football and get that home final we have to, first, make sure that we get a good result this week.
“It’ll be tougher if we have to play away in the first week of finals. There’s certainly a big prize on the end of this week, and we’ll be going out to make sure we get it.”
Adelaide will be without tagger Rob Shirley (hamstring) for the game against Carlton, but could be bolstered by the returns of Brett Burton (corked glute) and Nathan Bock (heel).
Scott Thompson, who finished Saturday's big win over West Coast on the bench, has a sore hip but is expected to play against the Blues.
Young gun Patrick Dangerfield will also be pushing for selection after impressing in his SANFL return from a back injury.
Porplyzia said the Crows could afford to recall the likes of Burton and Bock without upsetting the balance of the side ahead of finals.
“It’d be great to have 'Bocky' and 'Bird' [Burton] back, if not this week, for the first final,” Porplyzia said.
“I don’t think it’ll change the structure of the team too much. 'Bocky' has been there most of the year and Brett has come back in pretty seamlessly, so I don’t think that will be a major concern for the side.”
Bock first injured his heel against Fremantle in round 15 and was able to play through the pain for a full month before missing a game.
Porplyzia, too, is no stranger to playing with an injury on the eve of finals.
The gifted forward played out the 2008 season despite a nagging injury that saw his shoulder frequently pop out of its socket.
Porplyzia helped drag the Crows over the line in the round 22 clash with the Western Bulldogs, but sat out the elimination final against Collingwood after his shoulder started popping out doing simple household tasks like opening the fridge.
The 24-year-old said he trusted Bock to make the right call as to whether or not he put his hand up for selection over the next fortnight.
“If 'Bocky' feels like he can perform with the injury, if he was carrying it at all, and contribute to the team, that’s the only thing it comes back to. That’s what my decision-making was based around this time last year,” Porplyzia said.
“When I felt like I could contribute to the team, I put my hand up. When I no longer felt like I could do that, that’s when I made the decision not to go on.”
