Being the pessimist I am. If the trade does not get done this year, then i see Hogan will be off at the end of 2019 for little or no return for Melbourne. It seems like he wants to go home and he will eventually go home.
If by Wednesday he doesn't get traded, he needs to extend his contract for minimum 2 years, keeping him till the end of 2021. That way we still have some form of a bargaining chip in terms of trading for some value.
Either Hogan signs on for a minimum 2 years or he is traded for pick 5 future first round it's that simple.
On a side note, Hogan may want to consider how he is going to kick goals at Freo. Count the amount of demons before you hit a Freo player, a freo player who wants to head across to Brisbane in 2019.
