I think what you are saying aren't mutually exclusive.
My point is Soldo is largely a 1 trick pony, in most cases he does it quite well (he occasionally lowers his colours) but he really has very little that he can provide apart from a chopout in the ruck hence why he burns through so many minutes on the bench. Put it like this, he spends a 3rd of the game on the bench, thats 40 minutes out of the 120. Its way too many.
Those extra minutes are being taken away from players like Cotchin, who needs a but more recovery to impact. I think you are being a bit hard on Cotch here, he's largely been good this season. His best games seem to be those where he plays 70-75% of TOG compared to the 85% he used to play at his peak.
I think our balance was a bit off as well with other positions on Friday. Shedda was playing more as a small forward, along with George, Shai and MRJ so we were a bit short in the midfield. We need to rebalance both of these issues before we play Port as I feel both contributed to the fadeout we had. Add Ross only playing 66% TOG and it all compounded IMO. This is where Pickett is so important, as he will usually play 85%+ TOG, similar to Kmac and Hugo has been doing the same, so they are my preferred wing rotations. With the 3 of them, they ensure that 2 of them will always take the wings. and they also provide chopouts for some of the other mids.
IMO TOG %'s are super important for us these days, less so when we were younger, but a lot more so now so that our stars can stay fresher for longer. Thats where I feel the Cotch / Soldo issues are compounding rather than mutually exclusive, therefore if we have a ruck / forward that can play 80% off on ground, even if their impact around stoppages is weakened compared to Soldo, the overall benefit to the team is much more impactful.
Just on Edwards, we need to move on from him as a mid, if he plays, it has to be forward as he did on Friday, but we got the mix all wrong with all of MRJ, Shedda, George and Shai all playing a lot of time forward.
