If we are dumping Isaako then we need a WFB to replace him, so Trbo, Teddy, Ponga
We can't afford to wait on Mann's fitness if we are replacing Isaako with Teddy/Ponga as Isaako locks out early.
If we want Isaako+Wiliame out then its Trbo+HTW or 2 cashies.
if we want Isaako+Mann to Ponga/Teddy then any of those cows are possible.
