You can get LDU and Daicos without trading Doc though.
Try:
Gawn > Cameron
Neale > LDU
Flanders > Daicos via Davey and Chesser
You are losing Neale instead of Doc but you are getting LDU instead of Setterfield and not going into round 4 with 900k in the bank (which is a lot of money to have not doing you any good for a week or however long it takes you to spend it. Especially early in the year)
Having said that.... Your midfield is pretty bloody strong already, with Hollands as your first sub offering you maybe 70. Do you need LDU right now? My focus would be on those forwards. Fyfe, Flanders, Greene and Comben are not looking like doing you any favours. Really, they are looking more like boat anchors at the moment.
Your issue down back is Chesser but he's on the bench so isn't urgent. Your mids are fine. You have a ruck to fix. You are leaking points up forward and have two dodgy bench options likely to make you nothing really slowly. On bench so they aren't critical but there is a rookie on offer in Chandler that should sort you out the cash faster. You've got 166k bank and at a glance, all the good rookies but Chandler.
I'd say your first priority is Gawn, then your 2nd and 3rd priorities are forwards.
So Gawn > Cameron leaves about 320k
Flanders/Fyfe > Ziebell leaves either 280k or 220k
Greene/Comben > Chandler sideways
This way you fix your ruck injury and you halve the Fyfe/Flanders problem. If one of them is missing, you can either trade them for the cash boost this round from the other, or even trade the selected player so you can loop your forward bench because you kinda need to. It' really weak. Either way, Chandler projects as being a tidy F6 for you in the opening rounds. You should have only 220 - 280k doing waiting for the next round where you can look at correcting Fyfe/Flanders into Bowes maybe or I dunno, there's another couple like Croxier who missed round 1 and you get to take a look at. Don't forget Kozzy will be back for round 4 with a round 5 trade in maybe on the cards.
The issue is that you miss the big shiny player this week in LDU, Daicos and Setterfield. But face it, you were missing 1 of them anyway because of Gawn and, because you were swapping Doc for Daics and because your onfield midfield is already full, the benefit from bringing in LDU or Setterfield is marginal. You can't afford LDU without losing another premium and fielding Setterfield over Hollands/Mackenzie should only be in the order of 20 - 40 points for an extra 200k spent. I think that ZB offers significantly better prospect of returns than Flanders/Fyfe fo not much more coin and Greene/Comben > Chandler is a no-brainer.
HTH. Yours is a good puzzle. Gawn getting hurt has made me thankful I did the boost in round 1. I haven't had any injuries to worry about in round 2 (maybe Hopper) but had I have not boosted in round 1
and copped an injury in round 2 it would have stuffed me right up. Not liking being down to 30 trades already though
