I think something has happened and he has lost (some of) the players. Not all of them, who else saw Jack nearly tear up in the player huddle after the game. Jack still wants to be out there.
I also think we are suffering a massive structural deficit at half forward. TV failing has been a serious problem with the way footy is played these days. Melbourne have radically improved when they have had a half forward and a competitive attitude, we badly need one to kick to ATM. Griffs just doesn't seem to cut the mustard. We ought to even start thinking out of the box for half forward, maybe park Maric there.
