Yep Hardwick has just finished his 5th preseason and take a look at the difference in the side from his first game in charge to last night. It's changed greatly from then to now and there is still changes to be made to that side. Take out Thomas Grigg Grimes Newman & S.Edwards and replace them with Maric Deledio Rance McDonough & Lennon and the side will be much better equipped to play the game that he wants to play. Right now it's not and it's a combination of injuries/poor form and kids not quite being ready which is stopping it from happening.
Like I said in another thread earlier this week, take a clubs number 1 ruckman, top 2 midfielder and FB out of the side and then have a number of role players struggling for form and any team will be made to look poor. WCE last week against Geelong is a perfect example they went from a side that looked like a genuine premiership threat after 3 weeks to one that looked like us.
Not sure if you saw it during the week but even Cotchin come out and said that the players are to blame for our current predicament as they just aren't working hard enough or performing well enough for long enough in games. Get out best players back and get our role players back to playing their roles and things will get back on track.
I agree with the ins and outs you suggested but there is one big problem with that RT... Dimma will never take out Grigg, Edwards, Newman.
