I reckon Billy at 6 is madge saying "i want you learn at least 2 positoons in our team and that bench utility spot is yours until mam gets back". I also think the squad and depth is far better when the back ups can cover multiple spots. If billy can play 9 and 6 to a decent standard, rogers and madden, and smoothy plus paix could all be gone by the start of the 2026 season with bukowski coming through at 9 as well.
Then you'd have reynolds, mam, hunt, black, maybe even seigwalt, as halves cover. Mozer, hunt, walters and bukowski as 9 cover. Plenty...
