Most people will disagree with me, but I'd go the second option. Crisp has gone big lately and seems to be a nice point of difference. Having said that, I don't own Gaff so if he is frustrating you then get rid of him.
My question is, rank for next week. Witherden (if named), Ryan or Scharenberg. I need to play 2 of these guys and trade one out to get cash to upgrade Darcy to a premo ruck.
Definitely think Scharenburg gets played. Collingwood very DT friendly and three 90+ scores in a row. Ryan is a tough one and I would lean towards Witherden if named. Ryan wasn't in defence that much last weekend and looked a bit lost. Although that juicy half back Freo position is tempting. But Scharenberg and Witherden for mine.
Having said that Darcy has been solid and Nank/Soldo and then Luenberger isn't the most threatening finish to the season for him. Wouldn't be surprised to see him go 90 in both games. Not sure this would be my most pressing upgrade.
My plan would be if Witherden is named play him and Scharenberg upgrade darcy. Witherdon not named trade both he and Ryan out and upgrade there rather than Darcy.
