Just some maths on remaining trades.
Lets assume you used 2 trades after round 1, and the full 4 this week.
Then you have 22 trades left for 21 spots in your squad.
Once you make your 2nd trade in round 4, then there is 1 player who is guaranteed to stay in your team for the rest of the comp.
If you spend that trade on a cash cow you intend to replace, that means an extra player in your squad who'll be there for the duration.
If you use max trades for the next 2 rounds, there are guaranteed 3 players you will never trade out.
That assumes you don't have to spend any trades in injuries.
Its where guns and cows are rewarded this season. Personally, I have Ponga, Cleary and Tauamalolo (and maybe on Aubusson) but after that, every player in my squad is unlikely to be an ideal final 17 player. But unless I get real lucky with cash generation and injuries, some of them are going to have to be. I guess everyone has hopes Grant will score well enough to keep. Maybe Koroisau will be able to hang around.
I see people trading people in because they have a good run of 4 fixtures - is the rest of your team good enough to allow you to spend trades bringing in guys for form?
if you are making decisions between say Issako or Valentine Holmes - you really should do so on the assumption that they will be in your team all season - because a bad week or 2 with injury/suspension and they will end up with you by default
