You lose a winger or centre - you're toast. With a 4 man bench, you can't cure every problem without creating glaring new ones.
If a Centre goes down, it's really up to a 2nd Rower to slide out - then you're going to have pace problems, so they just need to change how they defend and train it every week. Moving a centre to the wing is often a lot simpler.
It's more what Storm do with NAS - you mis-match the defenders with the big man. Payne has some pace for a big man - you get him 1:1 with the half back or centre and you're at worst looking at a 2 man tackle not wrapping the ball - which means offload time to Staggs and co with a 2nd rower to beat. Even if he popped up wide 3-4 times a game, it would do damage.
