I think you could in theory play 4 of them down back provided they are agile/nimble enough to rotate on smalls as well and get the job done at ground level. Remember through our dynasty years we had rance/balta, grimes, astbury, broad, throw in vlas too as a medium.
No theory we used to do it as ive pointed out for years.Not just us you only need look at how the majority of teams in the comp structure up in the back half. Rance, Astbury, Grimes and Broad with the big bodied medium in Vlastuin there as well. Rance went in came Balta.
Astbury went we have Miller. We have drafted a beaut kpd in Gibcus.
Imo Gibcus and Balta should be our kpd set up. The question for me is weather Miller or Bauer is the third tall.
Bauer looks like he can play on all types to me, a bit like Grimes. Weather he ends up being good enough is what we need to find out.
Brown, Smith Trezise Banks there is some promise there to go with the big fellas. Even have some depth for the talls with Blight and Young.
Would be very tempted to see what Blight can offer as a forward. Shame Gray is injured.
