Premiums or Downgrades

[Flyn Ryder]

Current team is:

Backs: Fisher, Heppell, Goddard, Duigan, Stanley, Lower, Puopolo (Deledio Buckley, Otten)

Mids: Boyd, Swan, Gibbs, Bartel, Hartlett, Krakouer (Harris, Bewick, Jacobs)

Rucks: Cox, A.Browne (Sandi, Curnow)

Forwards: Franklin, Silvia, Pavlich, Goodes, Knights, Darling, Chapman (Tapscott, Matera, Richardson)

13 trades and $270,500

Basically I've been doing far too much sidewards trading and have a lot of $200k players on my bench.
This week I was thinking Darling -> Mzungu and Hartlett -> Premium (Who is the best option?)
After that, perhaps upgrade Duigan.
Should I still be thinking about downgrading or straight swap for Premiums as I have some money to spend?

First swap Gibbs into your Backline for Buckley, bench Puopolo. Upgrade Harris to premium , and downgrade Matera to Mzungu. I would hold Krak as it leaves a DPP link and Richardson is too big a risk to play now so Bewick stays and Matera goes. I would look at setting the mids first then the Backs.
