One of the big things I have noticed about this season under Voss is that players are given roles and the expectations are set for those roles and they are competing with others on the list for the team spots available for each role. Wings, small forwards, mid/tall backs, inside mids etc. They aren't playing players in the positions they aren't slated for, mids played as forwards, for example, like in previous years. That's one of the reasons I can see why Dow isn't getting a game. JSOS is a product of this, he is a tall forward competing with Charlie, McKay and now TDK, they just can't fit them all in the side and they won't play them out of position, unless by absolute necessity, (SOS rucking or Kemp as a tall back). Even if you categorise JSOS as a 3rd tall forward there is still only one place in the side for that position and they have gone with TDK this week.
I reckon their formula is
7 Backs, 2 tall 5 mix of lockdown/running/Intercept
3 Wings
7 Forwards 3 tall 4 small/Medium (Sometimes one of these will be a mid coming of Half Forwrd like Walsh has been doing)
1 Ruck (plus Backup from tall Fwd)
4 Mids (Mostly inside mids with run coming from wingers)
