I think with a 23 man squad you would hope we have the right mix of players to put out 2 different XIs with every position covered by someone who is comfortable in their role.
So our 1st XI might look like:
Moss
Fenton Dura Rossi Doyle
Lia
Roly Finkler
Kosta Krishna WeeMac
2nd XI:
Italiano
???? Fox ???? McGarry*
A-Rod
Ridenton ????
Rogerson Watson Parkhouse
*McGarry is out for months with a knee injury. Might not even still be contracted? Released for winter club football?
Now this is just indicative, obviously the 1st XI might be different. But still, we need a RB, a CB, a CM and probably another LB (at least as injury cover for the first half of the season). There's a few young guys in the setup who could fill some of those spots - Gulley, Rufer, Singh, maybe some more I haven't thought of. Still though it's obvious that we need defensive cover. And for all the talk of a RB we could actually use another LB and another CB still too, even if they're only young guys who are there for worst case scenarios like heaps of injuries and suspensions coinciding with an AWs game. I imagine Rufer or Singh will fill the last CM role.
