I sincerely hope he works out for your club. I'm also glad that Freo didn't pick him up as we have more than enough ruck stocks and he is an unproven KPP.
What would worry me though if I was a Melbourne supporter would be if his heart and soul will ever be in his footy at Melbourne when it is clear he wants to be back in WA. If he is to reach his full potential, he needs to be 100% committed to the club he is playing for. He is not starting on the best foundation for this to be achieved. Still, time will tell.
If I was you I'd worry more about how Freo's history of FUBAR trading has managed to combine with the even more FUBAR trading presence of Lyon to lose a player that nominated you as his club of choice.
