Israel Folau may finally see more action at 13 for the Waratahs this season following the departure of Adam Ashley-Cooper.
New head coach Daryl Gibson will consider using the Australia star in midfield to fill a major hole in the Waratahs' backline.
New signing Zac Guildford and veteran Mat Carraro are possibilities to step in, but Waratahs and Australia coach Nathan Grey believes that Folau would do a good job in the centres and is "comfortable" enough to move up from full-back.
"Where he plays will be dependent on where everyone as a coaching panel – and Daryl's the head coach – feels that he's going to add the most impetus to the side," Grey told AAP.
"If that's at 15 or that's at 13, then I'm sure he'll be looking to apply his skill set to the way we want to play and aid our chances of performing really well.
"Without a doubt, he's comfortable in that front line. There's some nuances you've definitely got to pick up and he's been working with Adam and with other excellent defenders for a number of years.
"So it's just a matter of making that decision and upskilling from there.
"Look, you can't replace an Adam Ashley-Cooper.
"It's a matter of someone else coming into that position and trying to take it to his level.
"[Ashley-Cooper] is a world class centre from a defensive perspective and he's someone who's already assisted a number of players in the squad in showing how that job was done during his time here.
"So a lot of it's guys having that understanding of what it takes at that level and it's up to us to upskill ourselves to be ready."
