Gia, Adams, Kruezer and McIntosh IMO wont be premium keepers and if you're going for the top prize will need to be traded
Gia can easily average 90+ this year. He wasn't that great last year and still managed to average 88. New coach, new game style which appears to involve a lot of short kicks, (i.e Hawthorn), so he can easily manage to improve his output by at least 5+ppg, which would put him in keeper status.
He has had a monster pre-season by all reports and its obvious watching him in the NAB cup, which is has scored very well in so far.
