Dangerfield was a free agent and Adelaide accepted that deal because it was better than the free agency compo.Bolton would be a good addition. Dangerfield at the same age effectively cost Geelong 9 and 28. I would suggest Dangerfield comparatively a more valuable player.
Bolton will be 26 next year and most AFL players don't go much past 30 and if they do they generally are on the decline. Mundys are the exception not the rule. Our list is youthful and strong - we don't need to squander picks in desperation. No way should we go more than one first plus trimmings.
