Yep, if idris/chee kam/ haleta or who ever is big enough to make a solid defensive unit outside and with a ET like on the inside should help - if they can work as a cohesive unit that would help Moses and brooks confidence in defence.
While he did miss some Moses has shown a lot of courage in his defence, more so than the previous season, last season he pulled off some good and important tackles.
Size isn't always important , one of the best defensive centres I have seen was Chris Johns from the Saints /Broncos in the 80's -90's
Made great reads and always would hit and stick
Johns wouldn't have been 90kgs , just great technique
Good attacking player as well , good speed
Just think he was a NSW player and had talent as well , go figure :crazy
Centres still need to be able to move laterally , that was Rowdy's big issue post hip and hamstring problems
I remember johns, good player and defender. Your right they don't have to be big, but most centres now days are on average bigger player. Yes lateral movement is important but mostly they have to gel as a unit.
They can't gel if they have a player that can't move laterally
A player like Tedesco will tear them apart
Much like we tore Penrith apart with Tedesco targeting Cartwright , once a player can get on his opposition players outside pandemonium usually ensures , creates the overlap
A simple matter of catch ,draw and pass then , try time
