I'm sorry you've lost me. There is part of an argument around better ball use in relation to Lennon, but Griffiths replaced him to try and stretch their talls and it worked in the first quarter as Dimma also mentioned, if Griffiths had kicked the 2 goals (as he should have) then it potentially could have been a different game.
The LLoyd / Conca one was because I think he wanted some additional midfield rotations. I'm less sure about what he was trying to achieve here and think Lloyd should have played but I'm not sure either really impacted too much on the result in the end. Conca did have his brainfade when we were looking to break and we were pretty open when he messed up that dinky kick but overall probably didn't impact the result.
The one area he really should have impacted the game was trying to get Cotchin into the game in a different way, he certainly should have been thrown forward to try and shake the tag as whatever Cotchin was doing wasn't enough to get rid of him, so IMO he should have been thrown forward as I think he would have had Jacobs in the air and could have impacted in the F50.
The other big one that people talk about was Jake Batchelors matchup and Grimes probably should have gone onto Waite but the real problem is the lack of flexibility that Batchelor provides us with, as he can only play on one type, too tall and he gets exposed, too quick and he gets exposed, too smart and he gets exposed. He wouldn't have coped with either Nahas or Thomas either so not sure of what we could have done.
Our real problem was our lack of flexibility which I think we've really tried to address in the off season. Our lack of flexibility has restricted our ability to mix things up on game day in the same way that we see the likes of Hawthorn playing. Batchelor has no flexibility and it will be interesting to see how we line up in the back half in 2016, will Yarran replace Batchrlor and take the smalls between him and Hunt with Grimes going to the 3rd tall player or does Yarran replace say Hunt. I hope the former. We've also relied on Cotchin too much as a ball extractor since Jacko and Tuck have retired, we've tried to address that with Townsend and Moore which is why I think at least one of them will be in the team from round 1, no idea which 1 is ahead at this stage, which should release this reliance on Cotchin and when he is tagged out of the game, someone else can support Miles with winning the contested ball, hopefully ending up in releasing Cotchin to be more damaging like his 2012 self.
So I kind of give Dimma some leeway on changing match ups as I don't think we have that right now, this is the difference between us being a good team that makes finals and us being a very good team that could challenge well into the finals. This is a timing thing in terms of our development from bottom rungers to where we are now and its the next stage in our development, adding flexibility and still being able to complete the game plan, instead of just being reliant on a handful of superstars to drag us over the line.
