Vodafone Fiji 7s team coach Ben Ryan says most of the players in the current team can play out of their usual positions.
Ryan says this is an advantage for the team as he can make positional changes during any game.
He says this will also keep the opponents guessing on who will start for the team.
Fiji will meet Canada in their first pool match at 6pm tomorrow.
They will then take on Japan at 9pm tomorrow before facing Argentina at 3.28am Saturday.
The Cup quarter finals will start at 8pm Saturday, Cup semis will start at 1.41am Sunday while the Cup final will be at 4.48am Sunday.
