Kurt's utility value is underrated. He's a better centre than he's given credit.
Kevvie's bench formula is: 1 regulation hooker, 3 regulation forwards. Which is fine until one of the backs goes down. Right now if a centre or wing is injured, we shuffle Capewell, and it's sorted. Billy can cover the halves at a pinch. He's not perfect, but he knows his role.
But take Capewell away, and things look very different. Neither of our hookers, starting forwards nor bench forwards are much use out wide. It becomes dysfunctional immediately.
