I would suggest everyone and anyone older than 22. This would include for mine - Foley, Jackson, King, McGuane, Moore, Thursfield, Tuck and even Newman (yes, big call I know
) Also to add to that list for mine is Connors, Edwards, Farmer, Gourdis, Morton, Nahas, Tuck and White.
I think you are right though MT - the teams further up the ladder have more depth to draw from when trading and those on the way back down the ladder such as the Saints may even trade some of their older 'stars' too.
The one factor though that we haven't taken into account is that their will not be a definitive list ie Top 5 players you MUST choose from. Really this rule will put the ball completely in the clubs hands. First each club will identify players they feel will be future stars (very risky except for the absolute standouts), gauge the general interest from other clubs and then use all this information to put a trade proposal to the GWS. GWS just need to sit back and let the clubs fight it out over the best potential talent and see which will give them the best trade that suits their list development.
For us, I think we should identify the future needs of the club (holes in list) and target players that fit that rather than just look for the best potential talent alone. If we can get a quality backman, ruckman or goal sneak who the GWS are happy to trade with us for a couple of our 'expendable players' this may be a far better strategy than going after the future No 1 draft pick and having to trade away a quality player/s.
Just my thoughts of course.
