I think the next 12 months will be hard for all concerned, regardless of the quality or application of the team. Old timers like macca or boyd will be under scrutiny every time the team doesn't perform regardless of their individual input, simply for what has transpired in the coaching. Whoever is brought in will be under pressure too to perform with the new coach, or be seen as disposable, with no buy-in for their investment by the management. Lastly Siebold with need to at least better Bennet's performance this year with a supposedly "better" team (despite every new coach being challenged by reforming the team to his image).
For mine, I think we will make the finals and depending on the how the halves perform, go atleast as far, but a new coach and the loss of some important veterans could lead us to fall short if injuries to key players happen (remember a new system will be in place and it will take a while for the players to buy into it).
Whilst everyone thinks maguire is easily replaced, I think he in particular will be the most missed. His energy and consistency, even amony the veterans still with us, is just not present. Lodge and TPJ might be able to be that kind of player, but they also might very well have moments of "madness" as young forwards (and gallen) are prone to.
