Senior coach Ken Hinkley said
"The boys have been in good form, we made only one change the week before last, and I think it's a sign we're pretty consistent with our group," Hinkley told portadelaidefc.com.au.
"Bobby Carlile came into the side for the Showdown, he's an experienced player, and other than that we haven't made a change.
"Other than that one change we're pretty happy with the team and the way we've been playing at the moment."
While the Power is likely to confirm an unchanged final lineup on Friday afternoon, Ken Hinkley is comfortable with the pressure for spots that exists within the playing group at this early stage of the season.
Aaron Young, Cameron O'Shea and Cameron Hitchcock came into the squad of 25 this week.
"Our SANFL players are in really good form - I reckon we've got seven or eight who are playing really well right now who we could consider playing.
"It's why we're in a good position at the moment, we've got a healthy list."
Port Adelaide will confirm its final team of 22 on portadelaidefc.com.au on Friday afternoon.
