I think the best thing they can do is assume Mueller is competent. In that, I mean he will both 1) uncover stuff that Trump and his campaign people did, and 2) not make false accusations.Trump's legal team preparing a "counter-report" in response to the allegations Mueller will bring against Trump
I suppose the biggest question is - if Trump didn't do anything and the report is being written as we speak, then how will they know exactly what Mueller is going to allege he did? And if they don't know what Mueller is going to allege, how can they offer a counter-argument?
So, assuming someone associated with Trump knows of all the illegal stuff they did, they can assume that's pretty much what Mueller will allege they did.
