They may have already traded out their R2 Xerri/Grundy/Marshall without knowing the score of Wilson.
Those three players were locked and irreversible.
For those with Sweet at R3 over the course of the round Sweet in the bubble with Livingstone playing after Wilson goes large increases access to his score.
For Sweet at R2, potentially with E on him (first game of round) and Livingstone at R2 still allows Meek to be bought back in, but not the likes of Grundy et al. Then those Grundy trading teams needed him either onfield or another donut.
Still think Sweet's presence is net uplift in people claiming Wilson's score. My leagues opponents, people with Wilson have got access to his score.
