After highly considering the floating donut strat, I'm not going to follow through with it because I think the best structure is to have 5 Premium mids + Moloney, with Wines and O'Meara. The vast majority of teams will have to play O'Meara and Wines every week, so I don't think I'm losing anything on them.
My own opinion, but I think it's going to be pretty hard trying to trade in those extra midfielders as they can cost around 100-150k more than Defensive/Fwd Premiums. I find it better to try load up on them and look for fallen defenders, forwards and rucks.
Running 3 rookie defence as a result, but not going to use a floating donut in defence either. Would prefer extra coverage.
Technically I do have a floating donut in Sinclair to connect with Cox in the rucks, but that one will only be used for the Captain loophole when possible.
