You do not get the point.
Its about the composition of the bench.
With a 6 man bench, you have a total of 2 props and 1 hooker, as well as 4 halves.
Even if Strange can play in the centre, then why have Mitchell there?
Cotter is a great player but he's not as good a prop as Smith or as good a hooker as Brailey.
If you're looking at individual choices, id have Mitchell and Teddy over Staggs and Walsh, but that doesn't matter.
The team composition and combinations are stupid.
And if you think having 4 halves instead of an extra hooker or prop is right, you're delusional or just arguing for the sake of it like usual.
