After six wins in their past seven, including four on the trot, the Panthers are shaping as the competition's dark horse.

Most sides don't know what to make of them - given a penchant for second phase play that sees them lead the league for offloads.

However, their ability to handle finals footy remains an unknown quantity.

Of the 17-man squad which will take on the Sea Eagles today, just four remain from their last finals appearance against Canterbury in 2014.
