Here it is.
F5 and F6 are going to absolutely kill you mate (Impey and JKH) They simply wont score enough.
Billings at F4 is dodgy too, wont score enough and is vest bait.
Grundy in the rucks is also an iffy choice IMO.
You are losing too much cash generation in your midfield by playing 6 premo mids as you are missing out on the other top mid rookies who will generate you cash.
