Yeah his JS probably isn't great but his form in the VFL has been good. Definitely one for the watch list if he plays.
Back to your point about a double downgrade being imperative this week - does it depend a bit on what rookies you already have? Eg. I was lucky enough to grab Newman & Williamson, I have 4 non-playing rookies - Hibberd, Strndica, Barrett, Eddy.
I'm also facing a donut with Nank in the rucks, but I'm starting to consider taking the donut because I don't like any ruck options.
