I know "experts" go on about all pro footy players that play center know how to play both sides of the field. That is just crap. They might be able to stand out there and play a game but most are ineffective on both sides of the ball. It's natural to have a dominant carrying arm and palm. You can see it with Hayne. He is terrible on the left because he is a dominant right hand carry. He carved for Australia as a right center. I struggle to name a player that can dominate in the centres on both sides of the field. For that reason I don't want to see Morgan on the left. He just can't be effective. Munster screams to be picked either as the left center or the 5/8th on that side but if you pick him at 5/8th you then have to find a left center and we don't have any decent ones.
I suppose you could move Chambers but I like him on the right. And Gagai can't be moved. His carries from the back and performances on the wing have been huge. So with all that dribble I would go Norman 5/8th Munster center.
