Good point, I actually think Goldsack is an excellent matchup against Riewoldt in terms of both size and speed. Losing Dunn will certainly make it much more difficult for us to get to the grand final, but not sure how well he would've done against Jack.
Treloar is instrumental though, our midfielder has looked highly exposable after his injury, consistently losing clearances (especially centre ones). I imagine against Richmond we would get absolutely smashed in the middle, with all of our midfielders being better at boundary stoppages.
Regardless, looking at our team, we simply cannot be a legitimate threat to Richmond if we're still carrying blokes like Langdon, Crocker, Appleby, Maynard, Mihocek, Greenwood, Sier...
However, if our injured players all return as planned,
FB: Brayden Maynard ~ Darcy Moore ~ Tyson Goldsack
HB: Jack Crisp ~ Matthew Scharenberg ~ Jeremy Howe
C: Steele Sidebottom ~ Scott Pendlebury ~ Tom Phillips
HF: Jaidyn Stephenson ~ Jordan De Goey ~ Will Hoskin-Elliot
FF: Jamie Elliot ~ Mason Cox ~ Alex Fasolo
R: Brodie Grundy ~ Adam Treloar ~ Taylor Adams
Int: Josh Thomas, James Aish, Chris Mayne, Josh Daicos
Could beat Richmond quite convincingly...
