Elliot Yeo vs. Brodie Smith?
Dylan Shiel vs. Ollie Wines?
Smith. He's done it before, and should improve if he doesn't get concussed. Yeo should benefit from a role mix change, but he averaged around 92-3 (on my count) in his mid games, so you'd be assuming no time down back at all for Yeo, just to match Smith's All Australian season. I think WC have traded for a couple of players who will take some mid time as well. Smith is also cheaper, slightly older, more experienced, seemingly more durable and was a slightly higher draft pick. Yeo is just outside my top 4 defs, with Smith inside at the moment.
Wines, given his SC pedigree (very similar to Selwood in the stats, from memory) and a slightly lower price. I investigated Shiel after BomberSam had him in his draft side and he is a more viable pick than I appreciated, with meaningful TOG upside and Treloar gone. Personally, I see no great need to pick these sorts of players this year though - I'd go another fallen ultra premium (there are about six in my view) or a Libba/JOM/Crouch type, in that order. Good luck.
