I love that every year the "old" superstars get written off. Scotland,Hayes,Pavlich,Chappy,ROK,Goodesy,Tuck. The only 1 who didn't have a good fantasy year was Goodes, mainly due to injury and change in role.
I'm picking ROK with swans easy start if he plays in the middle. Pavlich will be my fwd line POD. Even Bartel available in the fwds is too good to pass up.
29 - 30 odd is not old. Some people don't hit their peak form until later in their careers. Everybody is different and people like Goodes Pav and ROK are such professionals and take such good care of themselves and aren't partying hard in the off season like the younger blokes. They can be just as fit as at any time in their careers. Experience counts for a lot in this game.
