Will be what defines the best teams from the rest. Sideways trading premo's on the basis of their upcoming 3-4 opponents. Say you have Buddy and he has been scoring well but his next 3-4 opponents he historically struggles to score against, whilst say Goodes is playing teams that he absolutely dominates against in the same time frame. It might prove to be a strategy worth taking to trade out a super premo based on upcoming block of opponents then trade them back in when they're expecting a better run.
Also guns who are playing, but hampered by a slight injury that is effecting their output, trade them out until they are 100% fit again.
I can't see the casual DTmer putting in the time to do that much inseason research.

Think a lot more strategy will be needed now.
