Why would they change the setup? Because they said they would. But if you read my post it says they are looking for more of his outside mid role PLUS pushing forward.

Mitch Morton
Mitch went to the midfield halfway through last year, and towards the end of the season he played some really good footy for us as an outside mid. We're looking for that again, as well as him going forward. It's a big year for Mitch with the chance to solidify that spot.
Which points do you consider sceptical? Tigers whipping boy and mindset the jury's still out possibly, but the other 5 points are absolute fact and have to be considered when looking at a guy at his price.
I would've thought that it was straight forward that he might spend some time up forward. That's hardly defined as changing the set up, he's scored decently as a forward in the past so it's not too concerning if he can become a target.
You consider them, but those 5 games are worth looking at more than any other of his games. He performed well in that role, and you'd think at this stage that his primary role will be in the position where he excelled last season. There's plenty of other factors that could point to him struggling to maintain such a high output (similair to his scoring levels across those wing/midfield games), but I'm not assuming the coaching staff are decided on his role.
